Biology Question related to Evolution?

A protein similar to the mammalian hormone prolactin is found in amphibians and birds. In amphibians, such as newts, it causes the animals to seek water as they do when they lay their eggs. In birds, such as pigeons, it causes them to regurgitate material from the crop to feed their young. Mammals respond to prolactin by producing milk. How does the theory of common descent explain these similarities?

I have a male cockatiel age 7 years and a female 9 months.?

Last week the young female laid an egg on the floor of the cage. I bought a nesting box, attached it to the cage, and with a paper towel moved the egg into the box on soft material purchased with the box. I do not see either of the birds sitting on the eggs or even going into the box. Today I found another egg on the cage floor and moved it into the box as before.
I would like to have a baby cockatiel. Am I doing things correctly? If not, how should I proceed?

zebra finch advice please answer?

iv had a zebra finch(male) since march when i took him on cause his mate died and his owner want it to keep my siskin(a rescue bird) company, so i took him on. I have now taken on a female zebra who i found outside, she and my male have paired up, well i think they have. My male had a nest that he came with that had all the nesting material that was in it when he was with his old partner, and he was very protective of his nest. i took the advice that i got from a question i post recently, which was to remove all the nesting material from his nest an clean it so that he would allow the female to share his nest and hopefully begin to breed. he now allows her in the nest but he isnt building a nest hes just useing the nest box when he goes to bed at night. will he start to make a nest or will he just forget about it? i have put hay in the cage but he is still showing no intrest at all. any help will be great and any tips to get them to breed will be great!! thnks a lot

if she did lay eggs in the nest box but the male didnt make a nest will her eggs survive and hatch or does the male need to make a nest. when i put the female in at first the male mated her but they havent done it since (that i have seen) and he mated her on tuesday and there arent any eggs so i guess it wasnt sucessful.

Bird Experts please will you look here? A.S.A.P!?

I have a nesting box in my birds cage, I have 4 birds, 2 boys and 2 girls. I opened the roof of the nesting box and put seeds in there so that they can get to become familiar with getting inside there. My female Gel threw all of the seeds out. She stated bitting, and she started trying to get the nesting material out of the material box thinggy. She has always been around my Male Sky and they have always been kissing and I believe trying to mate. Is my bird gonna lay eggs?

I have a pair of “love bird” cockatiels that mate nearly every day.?

Last year, 3 eggs were laid, and totally forgotten. this year, 5 eggs have been laid, and at times, she sits on them. The question is this: Since they don’t have a nesting box, can these eggs hatch even though they don’t have the benefit of nesting material? Will she continue laying now that she is finaly sitting on them?

My lovebirds laid eggs and I need HELP!?

I have two lovebirds that I “rescued” and am still new to them. Yesterday I found two eggs at the bottom of the cage (I had not put any nesting material or nesting box in the cage yet). Neither of the birds were sitting on them. I came home today and now there is a third egg and one of them is sitting on them. Is it too late to introduce a nesting box and nesting materials? If not, can I use shredded newspaper or tissue or do I have to have the stuff from the pet store? Should I feed them anything special? Also, does anyone know if the male sits on the eggs because the one that is sitting on the eggs is the one I was told was a male. Any assistance would be greatly appreciated!!! Thank you.
