Wow Thanks Tracy, I love hearing about the family histories.
maggieblue:
When I was looking for background on this site I came across an article about Amelia's rehabilitation. She wasn't recovered enough for release until after Zeus and Hera had already paired up. This was like the Victory/Scout scenario in Colombus. There was concern that Amelia would immediately return to her nestsite with an ensuing fight between her and Hera with injuries and/or death to one or both. I can't recall where I read this, it might have been in the archived newsletters. I will try to find it when I have some more time.
carly:
Look at what happened at the Brighton site, the rehabbed tiercel flew right to the nestbox and huge, nasty fight ensued. Can you imagine if she had had eyases newly hatched, could have been like Ma & S2 in the Netherlands.
If they have established nest sites,I guess it doesn't matter where they release them but perhaps the decisions are made as TPC said based on the situation. Maybe some distance buys them a bit of time depending on what is going on at said site and what time of year it is. If it's 'courting season' and the hormones are a raging, then maybe a few weeks gives the hormones time to calm down and they'd think twice before fighting to the death? Whereas if hormones are in 'mating' mode then I would imagine they'd be keen to fight it out?
I'm just guessing...it was something Froona said about the way hormones affects their behaviour during courting/mating season that put it in my mind. She said when S2 took over the nestbox and refused to feed Ma's eyases, it was because her hormonal cycle was set to 'courting' so in her mind any food Pa brought was for her not for the eyases. Once that phase passed and she was calmed down..then she reverted to 'mom' mode and was able to mother the little ones. I'm explaining it in simplistic terms of course, as I don't have Froona's biological knowledge but I did get the gist of what she was saying. Perhaps the same logic applies here?

Correct me if I am wrong Tracy, but the biologists here said that you should always release injured or rehabilitated adult falcons in an area they are familiar with.
when they released the transmitter girl last year, they released her at the agricultural building , which is not far from the nest site. Because of the time of the release , they did not feel she would return there but she was familiar with the area.
The year before when the Balzac. girl and the transmitter girl fought , they released the transmitter girl just down the street. Well it was a ways down but she knew the area. she did try and return but was chased off by the Balzac girl
I love the rehabilators and I am not being critical of these ones. I am just confused that they would do that after what these biologists here stated.

I'm not a rehabber but as I understand it, it depends on when it is. We return rehabbed fledglings to their nestsites in the hope that their parents will continue to support them if the absence is short enough (up to 3 weeks in our experience). Longer than that, the rehabbers keep the birds and make sure they can fly and hunt on their own before we re-release them. I think release locations are a question of preference and what is best for the bird being released. Since young birds tend to disperse from the nestsite a few weeks after fledging, some adults do as well, some don't. We haven't ever had any conflicts between adults and offspring that have been missing for an extended period, but that is something I would have to consider before that kind of release.
Does that kinda/sorta answer your question? I am waiting for a response from a rehabber friend of mine, will tell you what she says when I hear something.

so I am happy that these 2 will raise another brood. Fingers are crossed for them
I was also upset about Amelia.
