photographing and learning about wildlife
The Tree swallow averages 13.5 cm (5 inches) long and weighs about 20 g. Their bill is tiny. The adult Tree Swallow has iridescent blue-green upper parts, white underparts, and a very slightly forked tail. The female usually has duller colors than the male, often more greenish than the more bluish male. The juvenile plumage is dull grey-brown above and may have hint of a gray breast band.
These birds were found in an open grassland wildlife sanctuary. There are many nesting boxes set up for them, and they use them during the mating season.
Although my captures show these birds angry with each other, they are a communal bird and after the breeding season live in large communities numbering from hundreds, sometimes to nearly 1000. It is quite a sight to see them flying together just before dusk. During the breeding season is about the only time I have seen these birds act as aggressively as I have captured them here. They are not your typical ANGRY BIRD!
