The nest appeared to be empty when I arrived. Waited a few minutes and was about to give up when I heard croaking coming from somewhere high up and south of the nest. Then noticed two CORA on the roof of St. Johns, and a third one perched high in a nearby tree on Morningside Drive. Appeared to be one adult and two fledglings that were almost the same size as the adult. The adult was keeping an eye on the fledglings as they clumsily practiced their flying. Observed the adult visit the nest site once. It landed on St. Andrew's head and peered down into the nest, then flew off. Its behavior made me consider the possibility of a young third chick or a deceased second chick in the nest -- which would mean I had been watching two adults and one fledgling -- though I don't think this was the case. Although the three were seen simultaneously, I never had all three perched together in full view side by side for comparison. However, I think the photos show two different fledglings, based on the amount of pink on the bill and gape. The croaking sound of the fledglings was similar to the adult but slightly higher in pitch.
