Whadda You Lookin' At? ~ While photographing these Cliff Swallow nests, the bird on the right was perched at the mouth of its nest, then turned to look at me. I captured that quick momentary look.
Domestic Squabble ~ I spent quite awhile photographing some Cliff Swallow nests. The swallows are very fast and very acrobatic, and not easy to capture in flight. It was fun seeing them in their daily lives, zipping in and out of their nests, and even squabbling among themselves, as were these two birds.
Defending the Nest ~ The Cliff Swallow on the left appeared to be defending his nest against on intruder. These types of encounters would take seconds, and off they would fly, only to return with mud or food, to go on about their business.
