Budgies are able to see ultraviolet light, which is involved in courtship
. The plumage patterns in ultraviolet are invisible to the human eye, unless you place your budgie under a UV lamp.

A UV receptor also may give wild budgerigars an advantage in foraging food. Although they feed mainly on grass seeds,
they also eat fruit. The waxy surfaces of many small fruits and berries reﬂect UV light that might advertise their presence. A quick and easy meal for a budgie!
Budgies can resolve rapid movement much better than humans
, for whom flickering at a rate greater than 50 Hz appears as continuous movement. Thus, humans are unable to distinguish individual ﬂashes of a ﬂuorescent light bulb oscillating at 60 Hz, but no more than that. Budgies have flicker tresholds of more than a 100 Hz!

Here's another breathtaking fact: budgies are able to detect slow moving objects. The movement of the sun and the constellations across the sky is imperceptible to humans. We are only capable of saying that the sun has gone a bit down or up, compared to half an hour or an hour ago. Budgerigars can actually detect this movement while it is happening! This amazing ability allows budgies to properly orient themselves in the wild.
Thanks for the enlightenment :)ReplyDelete
No problem :) You know I love to blog about budgies ^^ReplyDelete
Can they only see purple? none of anyother coloures??? :(ReplyDelete
No, they can see all the colors we can see too :) on top of that, budgies are able to see ultraviolet light, which we can't see.ReplyDelete
It is so atrocious to to cage flying animals and clip their wings for your fun and pas time is beyond me my son;s friend was getting his budgie put to sleep because they bored of it,so my son brout the budgie home but it pains me so much,we got another budgie from petco,so can have company,but many people advised us not to get another,because the budgie won't be dependent and attached to you,I can't understand people,why they are so cruel,how do they live with themseves?ReplyDelete
