I think the first one is a Zebra finch from memory of keeping them Mark,quite noisy little critters.You have managed to retain a decent amount of sharpness given the fact it was ruffling itself.The Peacock shot is nice,colorful and and has plenty of detail,worthy of a print I would say.
Edit: Just looking twice at that one Mark,I would say it seems slightly sharper on the fan of feathers more than the head,that may well be down to uploading and hosting.General rule of thumb if you are not aware,is when finishing your editing,or even if you are happy with shooting Jpegs and no editing,resize the image to whatever on the longest side you wish.Then give it a sharpen,or when you save the image use the "Save for web and devices option"
