June is when the first Black Oystercatcher chicks are born. Haematopus bachmani is their Latin name and they are found on the Pacific Coast, from Baja to Alaska. They are a noisy bird - a Sightings contributor deemed them "chattery." They nest on rocky perches and you will see their chicks look like little rocks, giving them a measure of camouflage.
This first photo was taken by Coastal photographer, Craig Tooley. There are three chicks in the photo.
And the photo below was taken by John Batchelder. I see only two chicks in John's photo.
To hear their call, here's a link to the Cornell Lab of Ornithology: http://www.allaboutbirds.org/guide/Black_oystercatcher/sounds
Thanks to John and Craig for allowing me to share their photos here. To see more of Craig Tooley's wildlife photographs, here's the link to his website: http://ruffimage.com/
