In spite of range expansion these subtly beautiful birds often fall prey to cowbird parasitism due to evermore cleared forests giving cowbirds more range.
In SE Arizona Hooded Orioles weave hanging "basket" nests from strips of palm fronds usually in Mexican fan palms. The orioles migrate north to the US to breed in spring and summer, returning to Mexico for the winter. If the birds are lucky they'll miss the usual seasonal trimming of the palm trees resulting in nest loss, egg loss, and/or young unfledged offspring death.
