Thanks, Al. Almost everywhere that you go in that area, you can find great shots waiting for you. And the conditions change constantly. It was a great trip!

Was having coffee out by the feeder and witnessed an "unusual" Family of Birds..

Chipping sparrowX cowbird 1


Chipping sparrowX cowbird 2

Chipping sparrowX cowbird 3


Chipping sparrowX cowbird 4


What we have here is a juvenile Brown Headed Cowbird and its Parent, a Chipping Sparrow. The Cowbirds lay their eggs in other birds nests...The Foster parent then raises the egg to adult at the expense of their own eggs. Often the cowbird chick will push out or just out compete the fosters real children. A few species of birds can tell the difference most can't. Quite the system they have, they have been known to commandeer over 200 Species of Birds. Earlier this year we had an eastern Phoebee pair with a Cowbird chick in it.

Nature ....
Its a tough call. I do not like seeing other species loose their chance at reproducing, especially in a time like this when song birds are in serious decline.. but.. the parasitism is spread out among many species so the impact is less.. Id guess crows and blue jays have a greater impact on nesting success as they are predators of eggs and chicks.

I think at the end of the day.. the system cowbirds use works very well for them.. which is why it exists.. what fascinates me is that they can be raised by many species and yet the offspring grow to recognize other cowbirds not the species that raised them.This chick wont grow up thinking its a chipping sparrow.. its really an interesting social system. If you look up "brood Parasites" you will see this behavior is not just a cowbird one.. cuckoos also as well as many insects and some fish use it.

Back to your question...Nature can appear cruel to us... but the goal is to succesfully reproduce. Somewhere along the way Cowbirds found this method to be the most successful way to go about it.
Hth,
Al
