Do hummers reuse nests? I know where an old nest is and I'd like to keep it if they're done using it. Todd in Owosso, MI
Hummingbird nests are fascinating. Female Ruby-throated Hummingbirds
alone construct cup shaped nests with a diameter about the same size as
a quarter. They start to build with bud scales and spiderwebs and then
camouflage the outside with lichen. To cushion the inside of the nest they use cotton or some other plant fluff like dandelions.
hummingbirds do fix up their old nest and reuse it. So I would just
leave the nest you found alone but check it next spring to see if you
are lucky enough to have the hummer return.
Also many people do not know that the Migratory Bird Treaty Act does make it illegal to collect nests of any native bird without a permit.
