They may only have a brain the size of a thimble, but it appears pigeons can categorise and name objects in the same way a human children learn new words.
A new study from the University of Iowa has shown that the birds are capable of learning to categorise 128 different photographs into 16 basic categories.
Scientists taught three pigeons to attribute different breeds of dog or types of shoe, for example to a particular symbol in exchange for a reward.
CROWS ARE PROBLEM SOLVERS
Crows are widely thought to be among the most intelligent of birds, but a recent study found they are even smarter than first thought, capable of solving complex tasks previously thought possible only by humans, apes and monkeys.
Most impressively, they performed the tasks spontaneously – without any prior training.
Two hooded crows were placed into a wire mesh cage into which a plastic tray containing three small cups was occasionally inserted.
The sample cup in the middle was covered with a small card that had a colour, shape or number of items pictured on it.
The other two cups were also covered with cards – one that matched the sample, and one that didn’t.
The cup under the matching card contained mealworms, which the crows were rewarded with if they chose the correct match.
The crows were then required to conduct a similar task but with images on cards that did not precisely match.
Researchers were surprised that the not only could the crows correctly perform these relational matches, with a success rate of 78 per cent – 50 per cent being regarded as chance – but that they did so spontaneously, without explicit training.
However, the researchers said it took their birds around 40 days to perfect the task of learning just 16 categories.
Professor Edward Wasserman, a psychologist at the University of Iowa who led the work, said: ‘Our birds’ rate of learning appears to have been quite slow. Human adults regularly learn 16 categories in the space of an hour, yet, pigeons took 45,000 trials to reach their associative limits.
‘Would children learn faster than pigeons? Almost certainly. However, our pigeons came to the experiment with literally no background knowledge.
‘They did not understand the nature of the “task”, they had not encountered these categories before, and they had empty lexicons.
‘Children, on the other hand, bring all of these things to bear on the problem of learning words.
‘Thus, the more relevant comparison group may be newborn infants, who indeed take 6–9 months to learn their first words.’
On each training day, the researchers presented each of the pigeons with 128 randomly ordered images.
Each image fitted into one of 16 categories – baby, bottle, cake, car, cracker, dog, duck, fish, flower, hat, key, pen, phone, plan, shoe, tree.
The birds then had to peck on one of two different colour symbols presented to them on a touchscreen computer – one that was associated with the correct category and the other the wrong category.
If the birds selected the correct symbol they were rewarded with a pellet of food. Incorrect choices plunged the birds into darkness foir a new seconds.
After the training, the birds were then presented with images from the categories they had not seen before to see if they could correctly attribute them.
Pigeons are known for their ability to find their way home, but the new study suggests they are even smarter
One of the birds reached an accuracy of 80 per cent, a second achieved 70 per cent accuracy and the third was 65 per cent accurate.
Writing in the journal Cognition, the researchers said their experiment was a very simple mirror of the way children are taught words – by their parents pointing to pictures and asking them to name the object.
They said: ‘Our paradigm is not a direct analog of human word learning.
‘Nevertheless, it does offer a unique biological model of a critical property of word learning – namely, the fact that a learner must map many exemplars to many categories.’
Professor Wasserman added: ‘Unlike prior attempts to teach words to primates, dogs, and parrots, we used neither elaborate shaping methods nor social cues.
‘Our pigeons were trained on all 16 categories simultaneously, a much closer analog of how children learn words and categories.
‘Differences between humans and animals must indeed exist – many are already known – but, they may be outnumbered by similarities.
‘Our research on categorization in pigeons suggests that those similarities may even extend to how children learn words.’
The scientists taught the pigeons to group images of real objects into the 16 distinct categories shown above
Pigeons are known to be smarter than many birds and their homing instinct allows them to memorise their location and find their way home from hundreds of miles away.
Professor Bob McMurray, another psychologist who took part in the study, said the results showed that human learning is not as unique as was previously believed.
He said: ‘Children are confronted with an immense task of learning thousands of words without a lot of background knowledge to go on.
‘For a long time, people thought that such learning is special to humans.
‘What this research shows is that the mechanisms by which children solve this huge problem may be mechanisms that are shared with many species.’
CROWS ARE ‘LEFT-BEAKED’ OR ‘RIGHT-BEAKED’
Researchers studying New Caledonian crows recently discovered the clever corvids display a preference for holding a stick tool on a certain side of their beaks – and this could be to make the most of their wide field of vision.
The researchers believe the birds may be trying to keep the tip of the stick in view of the eye on the opposite side of their heads, so they can see clearly in order to use tools in the most dexterous way.
Lead scientist Dr Alejandro Kacelnik, from Oxford University, said: ‘If you were holding a brush in your mouth and one of your eyes was better than the other at brush length, you would hold the brush so that its tip fell in view of the better eye. This is what the crows do.’
New Caledonian crows surprised experts with their ability to use sticks to extract larvae from burrows and, in captivity, retrieve food placed out of reach.
The study, published in the journal Current Biology, also suggests that the birds’ unusually wide field of vision actually helps them to see better with one eye.

Farmers cultivating fruits like grapes on ‘pandal’ are advised to erect anti-bird nets with subsidy under the National Horticulture Mission to protect the fruits from birds, squirrels, owls, etc., as the netting protects the crops from extensive damage to fruits and vegetables.
Anti-bird netting is an effective method for preventing crop loss usually caused by birds that invade the vineyards in flocks. Anti-bird netting can be done manually or mechanically depending upon the need. The anti-bird nets can also be used for holding animals in an enclosure, thus preventing any pillaging by birds and in some instances for keeping wild animals out and preventing consequent damage. With regard to aviary protection, wide-meshed nets are recommended.
Plastic anti-bird netting is a light weight but strong netting that will protect soft fruits and vegetables from bird attacks and browsing animals. Anti-bird netting can be used for fruit cages, protection of crops from birds, rabbits, squirrels and other similar pests, he added.
The plastic bird netting is lightweight, easy to handle and simple to install over fruit cages, directly over fruit trees and on vegetable or fruit growing areas.
The netting apertures allow smaller essential pollinating insects through and smaller butterflies while preventing birds. Anti-bird nets have a rectangular structure which creates a strong plastic mesh structure, making it easier to install and long lasting than the diamond mesh structured plastic bird netting.
Inspecting a field with anti-bird netting protection at Krishnapuram in the district, S. Raja Mohamed, Deputy Director of Horticulture, said 50 percent subsidy at the rate of Rs. 17.50 per sq.m. limited to 5,000 sq.m. per beneficiary was being given under the NHM to the farmers, who needed anti-bird nets.
As a promotional measure during the current fiscal, 1,000 sq.m. had been allotted to P. Ravichandran of Krishnapuram under this component with an allocation of Rs. 17,500.
“Farmers cultivating fruits like grapes and vegetables grown on ‘pandal’ may go for anti-bird netting with the NHM subsidy. While this effort fetches sizable assistance, the yield is also increased substantially by preventing invading birds and smaller animals,” Mr. Raja Mohamed said.

Some very interesting new research has uncovered something remarkable about pigeons. Apparently, they can learn much like a human.
“The research shows the mechanisms by which children learn words might not be unique to humans,” comments study author Bob McMurray, of the University of Iowa. “Children are confronted with an immense task of learning thousands of words without a lot of background knowledge to go on. For a long time, people thought that such learning is special to humans.”
McMurray goes on to say, “What this research shows is that the mechanisms by which children solve this huge problem may be mechanisms that are shared with many species.”
Obviously, a pigeon does not have the same capacity for information as a human, but the study suggest that they have, at least, comparable capacity for learning.
“It is certainly no simple task to investigate animal cognition; but, as our methods have improved, so too have our understanding and appreciation of animal intelligence,” explains study author Ed Wasserman, of the University of Iowa. “Differences between humans and animals must indeed exist, many are already known. But, they may be outnumbered by similarities. Our research on categorization in pigeons suggests that those similarities may even extend to how children learn words,”
He presents hypotheticals: “Would children learn faster than pigeons? Almost certainly; However, our pigeons came to the experiment with literally no background knowledge. They did not understand the nature of the ‘task’ they had not encountered these categories before, and they had empty lexicons.”
“Children, on the other hand, bring all of these things to bear on the problem of learning words,” he says. “Thus, the more relevant comparison group may be newborn infants, who indeed take 6 to 9 months to learn their first words.”

Two Aeroflot jets collided with birds in the past 24 hours, but no one was injured.
The pilots of an Airbus A-330 radioed air traffic controllers shortly after taking off from Moscow’s Sheremetyevo Airport on a flight to London to say that they had struck a large bird, Interfax reported Thursday.
“Nonetheless, the crew decided to continue the flight,” an official in Moscow’s air traffic control was quoted as saying.
The plane departed Moscow at 8:45 p.m. Wednesday. No serious damage was discovered to the aircraft after it safely landed in Heathrow.
The report did not say how many people were aboard the jet, which typically can carry 250-300 passengers.
The second bird strike occurred as an Airbus A-321 flight from Moscow was preparing to land at the Kaliningrad airport at 3:40 p.m. Wednesday. The bird hit the cockpit’s windshield, Moscow’s air traffic control said, without elaborating on whether the windshield was damaged.
Interfax did not say how many people were on the flight.

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?
HABITAT ANSWERS: 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 birdbarrier.com or 800-NO-BIRDS.com:
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, LLC
Known 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.
