The merlins nesting in MV this summer are in a decidedly natural nest. an old crow or hawk nest, not entirely sure. The location may be weird, but they chose it themselves, no human intervention whatsoever. I don't know about any other returning raptor species, but at least one is forging its own way. P.S. sorry if I fudge anything up with this, been years since I've been on a listserv. ______________________________________________________________________ Ohio-birds mailing list, a service of the Ohio Ornithological Society.
