A tufted titmouse is nesting a a nest box in our back yard.  She had six eggs 
prior to incubation.  Each time I checked during the incubation period, she 
refused to move off the eggs, and hissed and snapped at me.  When I checked 
the nest on Saturday, I found one very large baby and only three remaining 
eggs.  We strongly suspect that the nest has been parasatized.  We found a 
definite cowbird in a prothonotary warbler nest only a few feet distant from 
this one.  Is there any way to identify this chick as a cowbird?
