Andrés Capdevielle, Drirector of the Rehabilitation Center, said about this ringed hawk: "This Hawk was registered on 13-02-2012 as RECS N° 16. It was a fledgling of the nest located in the tipu tree of the Canal Viamonte. Personnel of the arboretum found it floating in the water tank next to the Viamonte hut. It was in a bad state and we thought it would not make it since it did not stand and was in shock. It was taken to the zoo to have some X-rays and a sanitary control. There it was registered as PCRAR N° 353. Back in the RECS, it was treated with antibiotics (due to water aspiration). It responded to the treatment satisfactorily, was active and fed on his own. Once the antibiotic intake ended and before it lost muscular mass due to enclosure, it was ringed with a black tag on the right leg and was released in the area of the nest on 24-02-2012."

These two juveniles present clear evidences that are males. When there is sexual dimorphism, that is the male differs from the female, juveniles in general look like the female. This similarity can lead to mistakes. For instance, to consider a juvenile an adult female when to top it all it is a male. Both species are black when adults. This characteristic is more advanced in the Yellow-winged Blackbird than in the Chestnut-capped Blackbird. The latter, for its part, is already showing the chestnut cap.
