Something Suspect

Remember the post I made earlier in the week about the cute Chipping Sparrow family?  Andrew and I both initially thought the baby bird closest to the lens was huge and odd looking. I wanted to investigate further but he was afraid the babies would fledge prematurely or us messing around with the nest would attract a predator.  The doubt about this bird not looking like its parents nagged at us all week and we both should know better. The day after I photographed the chipping sparrows I came home from work at lunch and there was a baby bird on the porch near the chipping sparrow nest.  I picked it up and looked at it and just as I decided that it was a baby robin and not a chipping sparrow momma robin with worm in tow dived bombed me from afar and confirmed my identification. I thought maybe there was a chipping sparrow nest and a robin nest in the same vicinity and that we had gotten into the robin nest, henceforth the bigger baby but that didn't make sense either due to the location of the nest in a bush. Anyway that night we got out the bird id book and looked at those baby chipping sparrows again as Andrew had doubts and swore that one was a cowbird baby.  Ok for the record I have never seen one single cowbird in this yard E-V-E-R.  This evening there was another baby bird on the ground and I was able to get a picture of it.  It was a babycow bird and guess what else?  Along came momma chipping sparrow who landed on the branch next to it and I actually saw her feed it a worm!! Crap!!  I hate that.  And I missed out on the photo of a life time of this tiny mother bird feeding this huge beast baby bird as the auto focus on my Nikon lagged and I missed the shot.
