Birds were one of the first animal species tested on their number sense. A raven named Jacob was able to distinguish the number 5 across different tasks in the experiments by Otto Koehler. [ 5 ] Later experiments supported the claim of existence of a number sense in birds, with Alex , a grey parrot, able to label and comprehend labels for sets ...
The researchers found that food-storing birds performed better in phase two than non-storing birds. [17] While food-storing birds preferentially returned to the rewarding sites, non-storing birds preferentially returned to previously visited sites, regardless of the presence of a reward. [17] If the food reward was visible in phase one, there ...

[292] The use of cotton swabs (aka cotton buds or Q-Tips) in the ear canal has no associated medical benefits and poses definite medical risks. [293]
In this situation the entire flock would search for food and the first to find a reliable food source will alert the flock and the entire group may benefit by this finding. [2] While this is an obvious benefit of the information-sharing model, the cost is that the social hierarchy of the flock may result in subordinate birds being denied food ...
Providing birds with a safe and warm space is just as vital as extra food at this time of year. "Robins often use nest boxes as roosting sites during the winter, so putting up a suitable nest box ...
Avian foraging refers to the range of activities and behaviours exhibited by birds in their quest for food. In addition to their unique body adaptations, birds have a range of described behaviours that differ from the foraging behaviours of other animal groups. According to the foraging habitat, birds may be grouped into foraging guilds ...
The birds were first trained on a limited set of paintings. The experiment has shown that a pigeon was able to obtain food by repeated pecking when shown a painting from Picasso; when it was a Monet, pecking had no effect. After a while, the pigeons would only peck when shown Picasso paintings.
