Yes birds are interesting. Never seen a European Great Bustard, but plenty of related species in Africa. It eats everything it can swallow, both vegetables and insects, mice and so on. Probably not snakes though...
There are more Mallards around us humans than wild in nature (or so it seems).
The very duck which all of us see. It is interesting to see the rutting male and how look-a-like he becomes the female, but you can tell by his beak and also his/her sound.
Redtailed Hawks were plentyful in Yellowstone this summer and we learned the difference between male, female and juveniles. Sometimes very tricky if you ask me...
Cheers
