Too many pigeons?

Authorities in Saskatoon, Canada, announced this week their plan to remove an estimated 350 tons of accumulated pigeon feces - roughly equivalent to 230 cars - from under a local bridge. While it represents an extreme example of allowing pigeon numbers to get out of control, it illustrates the need for an appropriate maintenance program to prevent the problem to begin with.

Pigeon poop is not just unsightly; the acid content can lead to deterioration metal, soft stone, plant and equipment. The accumulation of pigeon droppings can deface the finishes and represents a health hazard. Removal is not only difficult and costly but can cause more damage than the droppings in the first place.

Nesting material, poop, feathers and debris can block gutters and pipes causing water damage to buildings. The droppings provide ideal environmental conditions for the growth and proliferation of 

Pipes and catwalks coated in pigeon droppings become slippery and unsafe to use particularly in wet conditions. Startled pigeons may take flight suddenly and cause a hazard.

Long story short, don't let your pigeons get out of control!

Barcelona Puts Its Pigeons on the "Pill"

Nov 28, 2016 06:19 AM EST

The growing population of pigeons in many parts of the world is becoming a very nasty problem.

One of the tourist attractions in Barcelona and other parts of Europe is feeding pigeons in plazas and patios of historical landmarks. However, the birds have increasingly become a problem for the past decade as they tend to trash the city, turning it into a giant dump.

The birds have been reported to poo on not only historical landmarks and buildings but also on tourists. Local authorities have been continuously receiving complaints regarding this matter. The government believes that putting the birds on contraceptive pills may gradually solve their problems regarding waste.

According to a report from Express UK, early this year, there had been a proposal regarding the euthanization of the birds to significantly reduce their population by a huge percentage. However, the proposal received protests from various animal rights groups from all over the world. This leaves the government with a dilemma on how to reduce the bird's population.

Now, a new means of control has been put in place to replace the original plan of killing the birds. The birds will be fed contraceptive food to put contraceptive pills into the birds' system. It is expected that by mid of 2017, special feeding dispensers will be installed all over the city which contain contraceptive food.

The Barcelona government has considered expert advice to successfully perform the operation without harming the birds. Results will be analyzed after the first year to see how the new "feeding system" will affect the general health of the pigeons. It is also going to be checked whether or not such an operation will be fatal to pigeons. The operation is expected to cut down the pigeons' population by as much as 80 percent in the next five years. 

Singapore Reports Pigeon Numbers Drop After "Birth Control" Trial

The Straits Times recently published an article on feeding pigeons nicarbazin, the active ingredient in OvoControl, in Singapore.  Click here to view the original article.

SINGAPORE - Call it birth control for birds.

A corn-based feed containing a drug called nicarbazin, which stops female birds from producing eggs or causes them to lay eggs that do not hatch, has helped to reduce the pigeon population outside Masjid Haji Muhammad Salleh mosque by 60 to 70 per cent.

The population of 400 birds there has dropped to between 120 to 160.

The Agri-Food and Veterinary Authority of Singapore (AVA) revealed the results of the year-long trial of the drug outside the Palmer Road mosque after it had concluded last month (Oct).

Mr Mohamed Idris, secretary of the management board of Masjid Haji Muhammad Salleh, said: "There has definitely been a visible and positive improvement. A stark difference and the best thing is it was achieved without culling".

He said while the birds still find their way into the mosque sometimes, this has become much less frequent. Fewer people are getting soiled by the birds that lurk in the area too.

"In the past, the dropping might hit you as soon as you stepped out," he added.

He said that the mosque management is open to extending the trial and has discussed this with the AVA.

The drug does not harm the birds and is not toxic to animals or humans if taken in small amounts. It would take 40kg of the feed to see toxic effects in dogs and cats, and 60kg for a child.

Commenting on the trial's results, AVA said the drop is unlikely due to the effect of the drug alone, and that other factors may have contributed.

For example, the AVA found 15 dead pigeons at the trial site in April this year (16), which post-mortem examinations found were due to dehydration.

The agency added that it has been keeping watch on the area to prevent people from feeding the birds. Since October last year, it has issued around 60 warning letters and fines to individuals caught feeding the pigeons there.

Feeding pigeons is illegal and those found to have flouted the rules face a fine of up to $500.

As the effectiveness of the nicarbazin feed remains inconclusive, AVA started another year-long trial using the same feed at Waterloo Street outside the Sri Krishnan Temple, in September. There are about 150 pigeons there.

The Waterloo Street trial will also study if the level of human traffic, which is closely linked to the amount of food left for the birds, impacts the effectiveness of the feed. The birds will be fed once a day by a temple staff.

As of last month, the AVA had received feedback 13 times regarding pigeons in the Waterloo Street trial area since the start of the year. This compares to 20 times last year.

Overall, the AVA received 3,500 pigeon-related feedback from January to October this year. Last year it received about 4,000, an increase from about 2,500 in 2014.

It has also received some 6,400 feedback about all kinds of birds, including pigeons, over the same period this year. About 7,300 messages were received last year, and about 5,700 in 2014."

"Birth Control" for Pest Control

There are now four different contraceptive products registered by EPA for pest or wildlife control,

  1. OvoControl (nicarbazin) for pigeons,

  2. Zona-Stat (porcine zona pellucida or PZP), immunocontraceptives for horses (and many other large, wild animals including elephants, elk and bison),

  3. Gona-Con (gonadotropin-releasing hormone (GnRH)) by USDA Wildlife Services for white-tailed deer, and,

  4. ContraPest (4-Vinylcyclohexene diepoxide and Triptolide) by Senestech for rats.

Each of the contraceptives builds on unique technological platforms with a similar biological outcome - interference with the reproductive system to slow or stop population growth.

"Pigeon Control" Often Requires More Than Just a Plastic Owl!


At a pigeon impacted facility, plastic owls normally fail to keep the birds away and after a while, pigeons will use the owl as a convenient perch.  Pigeon abatement using OvoControl, birth control for birds, can manage down that problem population of birds.Trying to "scare" pigeons normally only works with real raptors - not replicas.  Take action today to control the real source of the problem - the rapid reproduction of these birds.For more information on OvoControl or Innolytics, please visit the company website at or give us a call at 888.908.0853.

OvoControl featured in Habitat Magazine!

OvoControl was recently featured in an article by Habitat, a publication for property managers of condos and co-ops.  Founded in 1982, Habitat focuses on topics that help educate the public on how to, "effectively govern and manage their associations and successfully contend with the complex issues of co-op / condo living."

Ask Habitat: Help! How Do We Fix Our Pigeon Problem?

March 2, 2015 - A READER ASKS:I live in a midsize co-op in Brooklyn. We have a huge pigeon problem. There are pigeon droppings everywhere. It's not just unsightly; there's so much of it now that I'm concerned about it becoming a health hazard. As far as anyone can tell, nobody in the building seems to be feeding them - we do have a policy in place against doing so. But is there anything the building can do to fix this problem and make the pigeons go away?


Pigeons find window ledges, rooftops, bridges, and warehouses to be ideal substitutes for the natural ledges in cliff sides that they have always used as roosting, nesting and sheltering sites. The good news is that there are some simple things that co-ops and condos can do to keep birds from their buildings - and the best part is that they are humane.

Stop Feeding the Pigeons

It's good that nobody in your building seems to be feeding the pigeons, but that doesn't mean that the building is not unintentionally doing so. Pigeons are going to hang around places where they can help themselves to discarded food and even crumbs. Keep the sidewalk clean and outdoor garbage tidy. Cleaning regularly will help discourage pigeons from gathering and setting up nests in your building.

Prevent Roosting and Nesting

Pigeons look for flat surfaces for roosting and nesting, so the building has to take steps to make flat surfaces unavailable to them. With the correct application of the right product, roosting structures can be rendered virtually pigeon-free. There are a variety of devices that can be used to change flat nesting spots into inaccessible spaces and prevent pigeons from roosting in areas where they're not wanted.The Humane Society recommends the following products, all of which can be ordered from

  • Attach wood or metal sheathing (Birdslides) at a 45- to 60-degree angle over window ledges and other flat surfaces to keep pigeons from landing.

  • Install "bird wires" to keep pigeons off ledges, railings, awnings, and rooftops.

  • Where the problem is more serious, consider using strips that give mild electric shocks.

  • Use netting to keep pigeons out of large areas.

Netting is probably your building's best bet - it's not only humane and effective but also a lot more cost effective.

Never use polybutylene gel, adds the Humane Society. Sticky gel repellents made from polybutene can harm all birds and any animal that comes in contact with it. The HSUS strongly recommends that these dangerous repellents be avoided at all costs. The feathers of any bird that comes into contact with the dense, sticky gel will become damaged, interfering with their ability to fly and to stay water-proofed. These gel repellents are not selective. Other birds are likely to land on the gel, get stuck, and die. The polybutene gels are particularly harmful to smaller species.

Planned Pigeonhood?

As year-round nesters, a pair of pigeons can raise a dozen or more young each year. If pigeons have plenty of food and space, their numbers can quickly increase. Fortunately, a bird contraceptive is available that limits growth of pigeon flocks. Ovocontrol bird food is "birth control" for pigeons. Innolytics, LLCKnown as OvoControl, pigeon contraception comes in the form of a kibble-type food, which causes birds that eat it regularly to lay eggs that fail to develop. Combined with exclusion and other humane measures to discourage roosting and nesting, OvoControl effectively reduces hatching rates in pigeons, thereby limiting flock sizes and diminishing problems associated with large numbers of pigeons.

Talk to Your Property Manager

Whatever you do, and regardless of how frustrating the problem, do not resort to poisoning them. In New York, it's illegal to kill pigeons. Your property manager can suggest viable options for your building and then present those to the board for a final decision. Your board should be involved in addressing any bird-related problems, because the solution will usually affect the building's exterior.
