Some birds from today

[Maydaywood]

I have no idea what species of birds these are so if anybody knows feel free to enlighten me. Also I know the lighting is mediocre at best but It was what I had to work with so I just tried to work with what I had. I had fun trying to imagine what they were saying at times while taking these
Critique is well appreciated if you have any. And on that note is the sharpness ok? My settings were ISO 800, 300mm, F/5.6 and shutter speed ranged from 1/100-1/1000 usually in the 1/300 range

I think (let me stress think) that you've got a tufted titmouse in the first two pictures. In the third picture, you've got some chickadees. The rest might very well be sparrows.

In bright sunlight, lower the ISO. For birds, I'd also stick to faster shutter speeds.
