The 55-year-old Iron Mike, who won’t face any criminal charges for his recent scrap with an airline passenger, befriended the legend during the height of his own iconic boxing career.
Now it appears that the former world champion has started a friendship with the late star’s grandson Nico Ali Walsh.
The youngster, 21, is already on his way to creating his own legacy inside the ring.
He holds a 5-0 professional record after his latest victory in Las Vegas.
Now it looks like he has been picking the brains of Tyson in order to further help him in his own quest for glory by paying a visit to the Baddest Man on the Planet’s home.
But it was not only boxing advice that Tyson had in store for the prospect.
During the visit, the much-publicised animal lover decided to let Walsh meet his famous pigeon collection.
And Walsh shared footage of him being taught how to hold the birds by Tyson inside the bird loft at his house.
The American has been smitten with the birds ever since he was nine.
Back in 2020 he posted a video of himself relaxing and feeding his pets ahead of his exhibition bout with Roy Jones Jr.
He has always had a love for pigeons, and revealed that it was the honour of one that drew his first punch as a ten-year-old.
He said in the past: “The guy ripped the head off my pigeon. This was the first thing I ever loved in my life, the pigeon.
“That was the first time I threw a punch.
“I have loved pigeons since I was nine. They were my escape.
“I was fat and ugly. Kids teased me all the time. The only joy I had was pigeons.”

RENO, Nev. – Last month, a couple of pigeons strutting through Las Vegas wearing cowboy hats captured the attention of the nation. They also apparently captured the attention of some Reno copy cats.
In a tweet posted Wednesday morning, Reno City Manager Sabra Newby reported finding a pigeon in northeast Reno wearing a tiny sombrero.
“I look out the window and there’s a bunch of pigeons and one of them has a hat on,” Newby said. “Who knew. In Reno now we have pigeons with hats.”
Newby had been on a ride-along with the city’s parking enforcement team checking on abandoned vehicles when she saw the poor bird.
The Las Vegas pigeons became famous last month after a Facebook video went viral. Two of the birds earned the nicknames Coolamity Jane and Cluck Norris, inspiring a parody country song and entertaining social media commentary, as well as national media attention.
But Newby said she was dismayed that someone in Reno would harm pigeons here. One of the behatted pigeons in Las Vegas recently died.
“It’s not really that funny,” Newby said. “Because somebody captured the pigeon and ostensibly glued it on. We don’t support that kind of activity.”
Newby said she reported the pigeon to Washoe County Regional Animal Control Services.
“Reno cares about our animals,” she said in a written statement. “They need protection and don’t need to become a punchline.”
While Washoe County Regional Animal Control has no jurisdiction over wild animals, the director urged people not to glue things to pigeons.
“Washoe County Regional Animal Services finds this practice of affixing any objects on wild birds disturbing, inhumane and strongly discourages this type of behavior,” agency director Shyanne Schull said in a statement.

Today, a Vancouver Island woman got the feathered reunion she’s been waiting six weeks for.
Sandy Bird lost her pet pigeon, Tweetie, in October, when the bird flew away, as it does, and landed on the wrong truck. The truck drove away and Bird was left without her pigeon.
To Bird’s distress, her bird wound up in a wildlife centre. The centre’s rules prohibited staff from releasing the pigeon back into Bird’s care. She tried to get her pigeon back, but instead it was released into the wild. The centre couldn’t tell Bird where or when Tweetie was being released.
This morning, Tweetie was spotted in a mall parking lot.
Bird said she looked for hours since the break of dawn for the bird in shopping centres and parks throughout Nanaimo.
Staff at a Chemainus office were keeping an eye out for the bird. Office worker Anita Morrill saw Tweetie through the window.
“He jumped down as soon as I saw him,” she said.
Staff called Sandy and told her to come collect her pet pigeon.
Bird said the pigeon is like a son to her.
“I am the happiest woman in the world. If I won the lotto I couldn’t be happier,” she said.
Bird said she would like to thank the viewers and listeners of CHEK TV and CBC radio.
“They’re the reason and you’re the reason he’s back,” said Bird.

A young woman in Fredericton is singing on the street to call attention to the disease that made her blind.
Erica Richards lost her sight last year after developing Cryptococcus meningitis.
Cryptococcus meningitis is a potentially fatal swelling of the membranes surrounding the brain. The disease is caused by fungus that lives in the guts of pigeons and other birds, such as chickens.
People can breathe it in if they’re exposed to pigeon droppings.
The 24-year-old was living in a house that had a pile of pigeon feces in the attic, and she also had a compromised immune system from chemotherapy .
“A reverse migraine — I needed light, I needed sound. I needed neck massages. Couldn’t lay down, couldn’t sit up. Couldn’t eat. I was vomiting. And then I started having double vision, quadruple vision, then seizures. And then I ended up in hospital,” she said as she described her symptoms.
Richards sings to supplement her $135 a month disability payment.
Kevin Forward is an infectious disease specialist who teaches at Dalhousie Medical School in Halifax.
“I think it’s pretty common sense. Move to avoid being in a situation where there are a lot of pigeon droppings, particularly if you’re disturbing them, cleaning them up, sweeping them,” Forward said.
“Those kind of situations should certainly be avoided. But if you’re in the park that has some pigeons around, I think the risk is infinitely small.”
Pigeons are part of the urban landscape, but they are known to carry a long list of disease-causing organisms — such as Chlamydia and salmonella.
That, along with complaints about them damaging roofs, led Fredericton to add pigeons to the city’s animal control bylaw last year.
Property owners are now prohibited from spreading feed or anything else that would attract pigeons.
Richards wants to make sure people know the risk of coming into contact with pigeon feces.
“To draw attention, to raise awareness so people will ask questions, so they will know what the symptoms are,” Richards said. “So that way, they can be warned ahead of time, before what happened to me happens to them.”
Next month, she’ll be going to a school sponsored by the Canadian National Institute for the Blind to finish high school and to get matched with a seeing-eye dog.
She hopes to go on to study law.

Growers often find bird nests around structures where food is washed, packaged, stored, and shipped. However, identification of these nests can be challenging. This article provides guidance on identifying nests of bird species commonly found nesting in barns, sheds, or other farm buildings. Most bird species included in this article are known to carry bacteria that cause food safety problems, such as pathogenic E. coli and Salmonella. However, some of these birds are also known to eat pest insects or rodents, so promoting nesting in appropriate areas can provide valuable natural pest control. Our article also makes recommendations for discouraging nesting in undesirable locations, such as food processing areas, and for promoting it elsewhere where birds can be primarily beneficial. We have organized the article by bird species that have invaded North America from Europe and Asia, and by species that are native to North America. Native species are protected under the Migratory Bird Treaty Act (MBTA) and cannot be harassed or have their nests tampered with.
Invasive Species
Figure 1. Group of European Starlings perched on a farm structure. Note the yellow bill and pinkish-orange legs that distinguish starlings from similar-looking native blackbirds. More identification information can be found online here. Photo credit: Olivia Smith.
The European Starling (hereinafter starling; Fig. 1) was introduced to Central Park in 1890 and 1891 by Shakespeare enthusiasts who wanted all of the birds in Shakespeare’s plays to be found in the park. If only they had never gone to the theater! After several unsuccessful releases, populations took off, and the starling has arguably become the most successful (and loathed) invasive bird species in North America. Though starlings are most numerous in human-dominated landscapes, they can be detrimental to native bird species due to competition for cavity nesting sites (Cabe, 1993). Although starlings do compete with more desirable native species for natural tree cavities, they have amazing flexibility in nest site selection and will also use cavities in structures (Fig. 2). Starlings construct nests inside of cavities with materials that can fall and dirty equipment or contaminate food with associated feces. Nests are easiest to locate by watching adults fly in and out of cavities. Starlings are known to vector pathogenic E. coli O157:H7 (Williams et al., 2011) and Salmonella enterica (Carlson et al., 2011; Kirk et al., 2002) and should be discouraged from nesting near food operations. Specific recommendations on starling nest management can be found here.
Starlings will begin choosing nest sites as early as February (Cabe, 1993) and can begin laying eggs between mid-March and mid-June, depending on latitude (Kessel, 1957). Birds typically lay around 4-5 eggs per clutch (a group of eggs) and have 1-2 broods (a group of nestlings hatched at the same time). Eggs are bluish or greenish white and approximately 2.7–3.2 cm long by 1.9–2.3 cm wide. Incubation generally takes 12 days (Ricklefs and Smeraski, 1983). Nestlings fledge (depart from the nest) on day 21–23 after hatching and typically continue to rely on the parents to supplement their food for 10–12 days (Cabe, 1993). Starlings are omnivorous (Wilman et al., 2014) and eat pest insects, predatory arthropods, and crops (Cabe, 1993; Somers, 2002). As with most bird species, the number of insects in the diet increases during the breeding season while chicks are growing and insect abundance is high (Cabe, 1993).
Similar to the story of the European Starling, the House Sparrow (Fig. 3) was introduced to North America in the 1850s and has now invaded all of North America. This species is highly associated with human-dominated landscapes. The House Sparrow has amazing nest site selection flexibility and can nest in nest boxes, inside and on buildings (Fig. 4), in stolen nests of other species (Fig. 3), or nest in and on trees. Intense competition for nesting cavities with native species can occur. Nests are constructed from a variety of materials such as dried plant material, feathers, or string. Like the European Starling, nests are most easily identified by watching birds fly to them (Lowther and Cink, 2006). Nest debris often accumulates under the nest location, causing food safety concerns when House Sparrows nest in food processing areas. This species is known to carry E. coli and Salmonella spp. (Morishita et al., 1999; Kirk et al., 2002) so should be discouraged from nesting near areas where food is present. Specific recommendations on House Sparrow nest management can be found here.

Nest building begins in February and March, and egg laying begins in March. House Sparrows have amazing fecundity, can have 4–8 broods per season, and can lay between 1–8 eggs per clutch (average about 5 eggs). Eggs are oval; about 2.1 cm long by 1.6 cm wide; and white, greenish-white, or blueish-white with gray or brown spots. Birds begin incubation after laying the final egg of a clutch. Incubation generally lasts 10–14 days. Chicks generally fledge after 14 days. Fledglings independently feed themselves after 7–10 days (Lowther and Cink, 2006). Insects, including alfalfa weevils and other pests, comprise about 68% of the diet of young birds (Lowther and Cink, 2006), while adults are primarily granivorous, often consuming livestock feed (Wilman et al., 2014).
Rock Pigeon (Columba livia)
Domesticated Rock Pigeons were introduced into North America by Europeans in the 1600s and readily went feral. Like the common name Rock Pigeon implies, this species historically nested on cliffs and in caves, so ledges of modern human structures are quite suitable as long as flat surfaces occur (Fig. 5; Lowther and Johnston, 2014). Nests are typically flimsy constructions made of straw, stems, sticks, or human objects. Rock Pigeons are known to carry pathogenic E. coli (Kobayashi et al., 2009) and Salmonella enterica (Kirk et al., 2002) and should be discouraged from nesting near food processing areas.
Nesting begins mid-February. Birds lay two eggs, and incubation begins after laying the second. Eggs are white and average 3.8 cm in length by 2.9 cm in width. Eggs typically hatch after 18 days, and chicks fledge on day 25–32. In some areas, Rock Pigeons can nest year- round due to chicks feeding on seeds and crop milk (a secretion from the crop of pigeons regurgitated to feed chicks). Mean number of nesting attempts per year is 6.5 (Lowther and Johnston, 2014). Adults are primarily granivorous (Wilman et al., 2014).
Native Species
Under the Migratory Bird Treaty Act, one cannot tamper with native bird nests or eggs. Therefore, with native species, prevention of nesting in undesirable areas and encouraging nesting in desirable areas is key (more details below).
The Barn Swallow is a species most growers love to see gliding effortlessly through the air eating pest insects (more information can be found here) but often causes disgruntlement due to its nesting habits. Historically a species that nested in caves, the Barn Swallow now primarily nests under the eaves of buildings or inside artificial structures (Fig. 7). Barn Swallows build open-cup nests from mud on the walls of structures. They often nest colonially (Brown and Brown, 1999). Pathogenic E. coli has been found in Barn Swallows (Nielsen et al., 2004), so nesting above food processing areas should be discouraged.
Barn Swallows have a vast global distribution, so there is considerable variation in life history attributes within the species. Birds typically begin nest-building within two weeks after returning to the breeding grounds (Brown and Brown, 1999). Females typically lay between 4–8 eggs (Shields and Crook, 1987). Eggs have an ovate to elliptical ovate shape and are creamy or pinkish white with brown, lavender, and gray spots. Egg size averages 1.9 cm long by 1.4 cm wide. Barn Swallows often have 2 broods per year but can have as many as 4. Incubation lasts about 12–17 days. Chicks fledge around day 18–27. For up to 2 weeks, fledglings rely on parents for feeding (Brown and Brown, 1999). Barn Swallows eat almost exclusively insects (Wilman et al., 2014; more information can be found here).
Historically, the Cliff Swallow nested colonially under ledges of canyons in the West (Fig. 8). Human land usage allowed a range expansion because modern highway culverts, bridges, and buildings became manmade “cliffs” for Cliff Swallows to build nests on (Brown et al., 2017). Like the Barn Swallow, the Cliff Swallow builds nests from mud, but unlike the Barn Swallow, the Cliff Swallow’s nest is enclosed and looks like a gourd (Fig. 8). Cliff Swallow colonies have been associated with increased environmental E. coli concentrations (Sejkora et al., 2011), so nesting should be discouraged above food packing areas.
Nest building typically begins within a few weeks of arrival to the breeding grounds. Arrival date and subsequent nest building varies by latitude and can start as early as March. The outside of nests are built entirely from mud, unlike Barn Swallow nests (Fig. 8), though birds do line the inside with grass. Clutch size varies from 1–6 eggs and averages about 3. Cliff Swallows usually have one brood but can have two if the first fails (Brown et al., 2017). Eggs are white, creamy, or pinkish with brown speckles or blotches. Cliff Swallow eggs average 2.0 cm in length by 1.4 cm in width. Incubation ranges from 11–16 days and averages around 13.6 (Grant and Quay, 1977). Chicks normally fledge between days 20–26, depending on the region. Fledglings rely on parents for food for the first 3–5 days (Brown et al., 2017). Like the Barn Swallow, Cliff Swallows eat almost exclusively insects (Wilman et al., 2014; more information can be found here).
The Black Phoebe (Fig. 10) has a small distribution within the continental United States but is frequently found on California organic farms foraging for insects. Natural nest sites include sheltered rock faces, streamside boulders, and hollow tree cavities. Like many other species in this article, human-built structures have increased densities of Black Phoebes by providing artificial nest sites. Black Phoebe nests (Fig. 11) appear quite similar to Barn Swallow nests. Nests are open cup, plastered to vertical surfaces, and composed of mud and plant material such as stems and small roots (Wolf, 1997). No current evidence has demonstrated Black Phoebes carry human enteric pathogens. However, Black Phoebes are known to frequent cattle troughs (Wolf, 1997), which is a known transmission point of human enteric pathogens between livestock and wild birds (Carlson et al., 2010). Therefore, growers should use caution due to little data existing on Black Phoebe pathogen rates.
Nest building typically begins in early March. Black Phoebes generally raise 1–2 broods per season with a clutch size of 1–6 eggs. Eggs are ovate to short ovate and white, sometimes with light spots around the large end. Eggs are typically 1.9 cm in length by 1.5 cm in width. Incubation averages 16–17 days. Chicks fledge between days 18–21. Fledglings are dependent on adults for the first 7–11 days (Wolf, 1997). Adults and chicks are almost exclusively insectivorous (Wilman et al., 2014).
The American Robin (Fig. 12) is, perhaps surprisingly, a thrush. To the disdain of many growers, its diet is largely comprised of beneficial invertebrates such as earthworms in the early breeding season, and switches to primarily fruits in fall and winter. It is adapted to live in many habitats and is common on farms and urban settings, as well as more forested settings like other thrushes (Vanderhoff et al., 2016). Like its habitat usage, its nest placement also has flexibility. Robins often place nests in shrubs, trees, or on structures, as long as the nest is on a firm support (Fig. 13). The nest is an open cup, constructed from mud, dead grass, and twigs on the outside, with a lining of fine dead grass pieces. One study found high prevalence of E. coli in American Robins (44.8%), though it did not distinguish pathogenic from non-pathogenic strains (Parker et al., 2016), so risk of American Robins carrying pathogenic E. coli is unclear. The USGS database Wildlife Health Information Sharing Partnership (WHISPers) reports several suspected cases of Salmonellosis in American Robins, suggesting they may vector Salmonella enterica to produce if allowed to nest near produce wash stations.
The American Robin is one of the most widely distributed species in North America, so onset of breeding varies by location, and occurs between April and June (Vanderhoff et al., 2016). Robins typically lay 3–4 eggs per clutch and have 2 broods per year. Eggs are a beautiful sky blue or green-blue color and average 2.8–3.0 cm in length by 2.1 cm in width (Fig. 14). The incubation period is generally 11–14 days (Howell, 1942). Nestlings typically fledge around day 13 after hatching (range 9–16 days; Howell, 1942). Parents typically begin a second brood within days of the first fledging. For the second clutch, once incubation begins, males feed fledglings while females incubate (Weatherhead and Mcrae, 1990).
The House Finch (Fig. 15) is native to the deserts and dry, open habitats of the southwestern United States. In 1939, several birds were released from a pet store in New York City, allowing a range expansion into the eastern United States. The western population has also expanded its range so that now the House Finch occurs across most of the United States and Mexico. Nests can be placed in a large variety of sites: pine, palm trees, cacti, rock ledges, ivy on buildings, street lamps, hanging planters, parking structures, lean-tos, window sills, in the cavities of various farm equipment, etc. Nests are open cup and built from grass, leaves, rootlets, small twigs, string, wool, and feathers (Fig. 16). In urban areas, birds will incorporate human items such twine, string, dog hair, cellophane, and even cigarette filters (Badyaev et al., 2012). House Finches are known to carry E. coli (Morishita et al., 1999) and Salmonella enterica (Kirk et al., 2002), so nesting near food processing areas should be discouraged.
Nest building begins in February in the southwest portion of the range and March in the northern portion. Birds can nest up to 6 times per year but have only been observed to have 3 successful broods a season. Eggs are pale blue to white with black and pale purple speckles. Egg shape is sub-elliptical to long sub-elliptical and ranges from 1.6–2.1 cm in length by 1.2–1.8 cm in width. Incubation can take between 12–17 days and averages 13–14. Fledglings typically take 2.5–3 weeks to feed themselves completely independently from parents (Badyaev et al., 2012). Young are thought to eat mostly weed seeds with very little insect matter in the diet (<2%; Beal, 1907). House Finch adults are granivorous (Wilman et al., 2014).
Like the Barn Swallow, the Barn Owl (Fig. 17) has a nearly global distribution. It is typically found in open habitats such as pastures and farm fields rather than closed, forested habitats. Barn Owls are nocturnal and most likely to be seen around dawn and dusk. The Barn Owl has a piercing shriek (example recording here) that can also give away its occupancy. Barn Owls nest in cavities including tree cavities, cliffs, church steeples, barn lofts, haystacks, and nest boxes (Fig. 18). Suitable nesting locations is a limiting factor for this beneficial raptor, so providing nest boxes is important (Marti et al., 2005; click here for more information on construction and placement). Barn owls are known to carry Salmonella spp. (Kirkpatrick and Colvin, 1986), antibiotic resistant E. coli (Alcalá et al., 2016), and Campylobacter spp. (Molina-Lopez et al., 2011), perhaps from feeding on mice carrying these bacteria.
The Barn Owl does not usually build nests, though some dig burrows in arroyo walls in Colorado and New Mexico. Because of its wide distribution, egg laying initiation date varies and can occur year-round. One brood is common for birds in temperate regions, but some pairs have 3 broods per year. Average clutch size ranges from 3.1 to 7.2, depending on location. Eggs are short sub-elliptical, are about 3.2–3.4 cm in length by 4.0–4.4 cm in width, and dull white. The female incubates eggs for 29–34 days. Fledging date varies based on location. In England, first flight is usually day 50–55, whereas in Utah, mean fledging date is day 64. Fledglings are dependent on adults for 3–5 weeks. Fledglings are clumsy until they gain enough strength and agility to fly (Fig. 18). Chicks and adults eat the same diet, which is mostly small mammals, including common rodent pests (Moore et al., 1998; Marti et al., 2005; Wilman et al., 2014). However, evidence that Barn Owls increase yield through pest control services is still sparse (Moore et al., 1998), though Motro (2011) did find an estimated alfalfa yield increase of 3.2% due to Barn Owls, equating to $30/ha per year.
Nest Location Management
It is illegal to tamper with nests or eggs of native species, so deterrence of nesting in unwanted locations before it begins is important. Avoid using poisons or methods that can harm or kill native species. Below are a few commonly recommended methods for deterring bird nesting on structures. More research is needed to test the efficacy of listed methods. Most methods are best initiated and maintained prior to the onset of the breeding season.
Block cavity entrances using mesh, wood, or other barriers (see nest in Fig. 2 above for an example this method could help with). Place netting carefully to avoid birds getting trapped inside (but see Fig. 4).
Create slopes on ledges by placing boards at a 45 degree angle so that species like Rock Pigeon cannot build nests. If a board doesn’t work, try a loose spring that creates an unstable surface for birds to build on. Spikes are also an option, but be aware spikes can kill birds. A quick internet search shows many examples of nests built on top of spikes, suggesting they are ineffective, and will also show photos of impaled birds.
Create a visual disturbance near nest sites by using flashing lights, placing mirrors on ledges, or hanging mylar tape. However, species like the European Starling are extremely smart and aren’t fooled for long with these methods (Belant et al., 1998).
Place plastic predators near nests. These need to be moved frequently to continue to deter birds (Belant et al., 1998).
Use noise machines that project bird distress or predator calls. However, there is no current evidence to suggest this method works.
Plant shrubs that provide good nesting habitat away from structures. Try planting near crops where birds will eat pest insects (like apples; Mols and Visser, 2002), but avoid placing next to crops birds will damage (cherries, blueberries, grapes; Somers et al., 2002). Prior research has demonstrated pest control services increase near natural habitat like hedges (Boesing et al., 2017).

Q. What can you tell me about pigeons’ nests? We just moved into a fifth floor apartment and there’s what looks like some kind of a bird’s nest on the ledge around our balcony, except it has sticks and debris in it. If it is a pigeon’s nest, will they come back to the same nest this year?
A. A ledge high on a building would be a typical nest site for pigeons (also called rock doves) since their natural nest site is in caves or crevices on rocky cliffs. In urban areas, pigeons nest in a variety of sites, but rarely in trees. Their only requirement is a dry, protected area and a flat surface upon which to nest and perch. Nests are usually high up on roofs, ledges, eaves, attics, or steeples, or under bridges or overpasses.
The male starts the nest building process by sitting on the nest site and calling for a mate. Once he has attracted a female to the site, he begins the search for nest material, bringing a single twig at a time to the female who tucks it in around her. During the day, the male sits on the completed nest that usually contains one or two eggs. The female takes over nest duties at night. Pigeons can nest year round and can produce up to 10 young a year.
A pigeon’s nest is not a thing of beauty; it’s rather a mess. It’s made up of a conglomeration of sticks, small twigs, grass stems, pine needles, and debris — all piled together with a small cup depression in the center. Nests that are in continuous use are soon full of feathers and droppings. Unlike most other birds, pigeons do not remove the droppings of the young from the nest. The accumulated droppings tend to cement all of the nest materials together into a mound. And, yes, the pair usually does reuse the same nest site. They add new nest material right on top of the old sticks and droppings. Reused nests can even contain unhatched eggs and mummies of dead pigeon babies. Nests that have been reused for 3 to 4 years can be almost 8 inches high by 20 inches wide and can weigh more than 4 pounds!
You should discuss the problem with your property manager. You don’t want a pigeon’s nest on or near your balcony. The nest can harbor parasites such as bird mites and lice that can bite people. Droppings below the nest can deface the building, sidewalks, and cars, and large accumulations of droppings may contain disease organisms. Whoever removes the nest should wear gloves, and should discard the nest in a sealed plastic bag.
There are various types of deterrents and repellents that can be used to keep birds from nesting on the balconies or ledges of your building. A reputable pest control company that specializes in bird control can discuss the options.
