Detalhes da observação
One of the juvenile BH Cowbirds was located close to the NE corner of the park. The other was located almost directly in front of the library, so they were obviously two different birds, being fed by different Junco parents. Interesting to see Parasitism first hand. It's amazing how hard the Juncos have to work to feed birds much larger than themselves. In neither case did I see juvenile Juncos present, which leads me to surmise that the cowbirds must have hatched first and demanded so much attention of the parents that the Junco eggs may not have hatched. However, I have no empirical evidence to back up this thought.
