That Bird Blog – Bird Care and History for Pet Birds

If you observe wild birds, you’ve no doubt marveled at their ability to fly through dense brush without touching a single branch.  In NYC, I’ve twice been surprised to see pigeons flying at full speed through amazingly tight spaces when pursued by Red-Tailed Hawks.  Bats utilize echolocation to perform similar feats, but with few exceptions (i.e. the Oilbird, please see below), birds lack this adaptation.  So how do they do it?  According to a recent study (Current Biology, Oct., 2011) at Australia’s Vision Center and the University of Queensland, some species rely upon vision alone.

“See-Compare-Adjust Course”

Researchers worked with Budgerigars (Parakeets) that had been trained to fly an indoor course that allowed for careful monitoring.  They were able to show that the birds used their vision to sense and compare the speed at which they passed background images, and then adjusted their flight path accordingly.  Read More »

Cornell University researchers have just revealed a most surprising bit of avian news that may show why Green-Rumped Parrotlets (Forpus passerinus) and their relatives are such good mimics.  Field research has shown that parrots actually label each chick with unique vocal signature –essentially a name.  The chicks and other parrots imitate these names, and use them when communicating with one another!

Why Mimic Speech?

Everything in nature has a purpose, and so ornithologists have long wondered why parrots have such extraordinary abilities to imitate speech, sounds and the calls of other birds…surely it cannot be just to entertain their owners!  We now have evidence that mimicry is likely vital to parrot social structure and survival.

It’s well known that birds exhibit an extraordinary degree of care and protectiveness towards their chicks…having been attacked by avian parents ranging from owls to ostriches, I can vouch for this firsthand!  As impressive as this may be, most folks tend to accept it as a matter of course – the survival of the species, after all, depends upon the new generation.  However, an amazing new study at the University of Bristol (UK) has revealed that female domestic chickens actually seem to exhibit empathy – that is, the ability to share and be affected by the emotional state of another individual.
