Hi Gene,
Deborah Allen and I think you have a juvenile (first-year) RL Hawk at Croton. The tail band on the underside of the tail is light (grey) and not dark (almost black). This is characteristic of young RLs. Adults have a black terminal band (males darker than females; and adult males have a few more thin bars on the underside of the tail than do the adult females). As in most raptors, females are larger than males...So we think you have a young RL - but we cannot sex it based upon your photos (size is difficult to judge in photos). Your final photo of the RL (perched showing top side of tail) shows a strong (dark) tail band...if (for whatever reason) the underside tail band was this dark, then we would agree that you have an adult female RL...but all your other shots indicate to us you have a first-year bird, sex unknown...We would say you have a light morph bird too...(Bill Clark might call it an intermediate morph - since there can be much lighter RLs.)
Several RLs now appearing in the area - Meadowlands (NJ) seems to have several...at least one place in the Bronx has a light morph annd a dark morph.
Best Wishes,
rdc/nyc
Thanks for the detailed information, Robert. As to the sex, even though the tail band is lighter in the BIF photos than the perched picture, multiple bands (male) are not seen. Also, from the BIF and perched photos a nearly complete dark brown belly is viewed. I agree that size comparisons, and therefore sex, cannot be made from the single bird photos.
