You KNOW that I love the Osprey. :heart:
What was going on/what did the behavior mean? I am by no means an expert, ;) but I did spend a LOT of time watching and listening (very critical) to the Osprey, so this is what I know. Juvies almost always return to the nest for food/meal time, which might be why the juvies were hanging togeather (they also just hang together when young). The parent might have been enticing them back to the nest, as it probably was their first flights. However, the juvies might not have been siblings. Osprey are very tolerent of juvies, so it isn't uncommon to find an adult feeding someone else's kid! That juvie might even spend the night in the nest. I've seen the osprey filling the sky several times - only once being territorial. The other times had the osprey flying, singing, and socialing together for lack of a better description. There were no territorial lines. The friendliness has happened after fledging (remember, they will head south in a month) - maybe this behavior is to establish lines of communication for the long migration south? Or maybe to establish those lines (friendlies) for the juvies? Who knows? Great pics Lou! :thumbsup: Janet Title: Re: Ospreys at INWR Post by: Joyce on 18-Aug-09, 08:37:03 PM Enjoyed yor pics Lou. I really like the one of the adult landing in the tree with the 2 juvies.
Thanks Janet. Interesting social behavior after the juvies have fledged. Are Osprey more social than independant? Is that why Osprey can have nests close to one another? At one time, the nests were lined up in a row next to the highway, as you approach the Montezuma Wildlife Refuge.

Joyce I don't know for certain, but after 3 years of solid observation, I can say that once the kids have fledged that the territorial lines get smoothed out. As for nests very close together, THAT is evidence of very good fishing grounds, which I suspect has more to do with tolerance than anything. I do know that "my" local eagles became very scarce when the osprey returned, which could be because of migration. I only ever saw one territorial battle between osprey and it was the cries that got my attention. Osprey juvies return after about 2 years in SA to make their own nests in the "old neighborhood" - perhaps that leads to more tolerance? Of course, THAT is a good news/bad news thing because I can't imagine every telephone pole in the area being covered with osprey nests. I also think that it was the returning juvies/adults that caused the territorial battle last year. Bottom line - don't know, but making a good guess. |
