Thread subject: reasonable to assume 1 male and 2 females?
Name Date Message
Dorothy 07/07/04 08:25 pm I've been hearing that female raptors tend to be larger and the males sleeker. Can we say Spirit is male and Peace and CZ are females? Can I go out on a limb (groan) and speculate that males tend to be better fliers too because of less body weight? (Hey, I see Spirit grabbing a meal and eating it!)
Marie 07/07/04 10:35 pm I think you can definitely go out on a limb re. body weight and agility in flying. I was told that by the Bird experts that is why male Eagles, Ospreys and Hawks and birds of prey are smaller so they can be good providers/flyers for the family amongst other things. Smaller is better in this case so that they are more agile and can manouver more quickly when catching prey, than a bulkier female.
Tiger 07/08/04 04:56 am I wonder if this may be a discovery? Up to now it has been thought that one cannot really tell. However this nest is presumably one of the best observed ever and we seem to all agree about our conclusions.

It is a pity that we will never be able to prove whether we were right or not.

For the record I think Spirit is male and Cz and Peace are female.

Celeste 07/08/04 05:49 am I agree. Once again, this nest has provided insights that I think are "changing" what has been written in the past. However, it would be great if the DPOF found someone to "comment" on our observations.
Dorothy 07/08/04 11:21 am I mentioned this because recently observed the Harrisburg peregrine falcons at the Rachel Carson building - there were three males and one female judged by their weights at banding time; the female was the largest (and loudest); one male was taken by an intruder, the other two males have fledged successfully, one being called a great ("ace") flyer; the female has fledged but continues to come back to the nest box ledge and waits for parents to bring meals (sound familiar!) --she is big! So I can't help but remark on some similiarities among these raptor fledglings.
