I've got two male Zebra Finches who have been very relaxed with each other since the death of the last female bird in the cage. I've got Sanchez and Shamar, Sanchez has become surprisingly hyperactive since I got him a few months ago, I figured he must have been adjusting to the move.
Sanchez (I'm almost positive) seems to have these fits in the morning when I open the curtain to their outdoor window, he makes raspy chirp sounds that are kind of like hissing, and he begins wagging his tail feathers almost as if they're vibrating. The two of them seem to be hopping around as if Shamar is being pursued by Sanchez. Is Sanchez fighting or trying to mate with him perhaps?

My other question may be silly, but I can't tell exactly how smart these birds are. I'm familiar with dogs being obsessed with food, and cats being snoops. But sometimes I feel like my birds are "squaking" rather than their usual beeps and chirps, and when I change their food and water, they both immediately go for it and stay quiet for a long time after. Do they have a tendency to give up on food in their dish before it's empty? Do they refuse to drink water that's been soiled? And are they aware that a large human figure dictates their food? I really feel like I should have read up on their behavior
