It’s October, and many people who closely track their annual migrations are getting ready to wave goodbye to the last hummingbirds of the year.

“Two residents and a migrant are preparing to leave i.e, nectaring even after sunset. In most years, resident hummingbirds leave on Oct. 2 but migrants keep coming until Oct. 10,” Journey North participant million.blossoms wrote from Carmel Hamlet, New York on Oct. 1. “Our cool temperatures (60s/40s) have driven away butterflies and birds earlier this year. So, it is unlikely hummingbirds will stay here longer.”
