I grew up near the Mission San Juan Capistrano which is world-renowned for the Cliff Swallows that return to it on the same day every year for nesting. Little did I know that we have several different species of swallows in our area - the Tree and Barn species being overshadowed by their "famous" cousins.The San Joaquin Wildlife Sanctuary has built nestboxes for the Tree Swallows all over the Sanctuary and it is amazing to see hundreds of them swooping and diving over the ponds and darting in and out of their nestboxes. They are incredibly agile flyers - scooping up insects in mid-air and grabbing bugs or sips of water on the wing from the surface of the ponds. Plus - I can't resist that gorgeous blue/green iridescent color!
This bird in full blue/green plumage was sitting on a branch overlooking the more grayish bird in some of the following shots. I am assuming this is an adult that was keeping an eye on a recently fledged juvenile.
This one just has patches of iridescence and was much less wary of my presence than the adult above. However, now that I look at the Cornell site - this may be the female.
Did seem a lot more interested in preening than in keeping an eye on me or moving away...which is how I was able to get better shots of this bird than the adult in the first photo.
One last stretch after preening...
...and it was ready to pose...
...and pose
And then stretch a little more...
Maybe it's the extra fluffiness that says "juvenile" to me...
Love the iridescence! You can also see this bird is banded.
And the adult has finally had enough of me! But does show off its leg band in this departure shot.
