Rare Hummingbirds In November

It’s November, but are you keeping your hummingbird feeders filled?  Is your salvia still blooming?  If so you may see a hummingbird that’s rare in Pennsylvania.

Rufous hummingbirds (Selasphorus rufus) breed from the south coast of Alaska to western Montana and spend the winter in Mexico and along the Gulf Coast. (Click on the range map to see details.)

However, a few have compass errors that lead them east instead of south.  Often these are immature birds who’ve never made the trip before.

Rufous aren’t the only western hummingbirds that make this mistake but they are the most common.  Allen’s, Anna’s, calliope and black-chinned hummingbirds also come from cool climates so they can survive Pennsylvania’s autumn weather but they must have food — midges and other insects, nectar, or sugar water.

On Halloween Donna Foyle looked out her window in Pittsburgh and saw a visitor from the Pacific Northwest.  A rufous hummingbird, pictured above, had flown in for a sip at her feeder.  On Saturday afternoon 3 Nov, Bob Mulvihill banded it and confirmed it’s a first-year male Selasphorus rufus.

It’s unclear how long this bird will stay in Pittsburgh but others may come.  To give you an idea of the numbers, during the winter of 2012-2013 one hundred vagrant hummingbirds were reported in Pennsylvania. 48 of them were rufous. 

So keep your hummingbird feeder filled and shelter your blooming salvia.  If you see a hummingbird this fall in Pennsylvania, contact one of the hummingbird banders listed at the end of this 2016 eBird article by Wayne Laubscher and Doug Gross.   In Pittsburgh contact Bob Mulvihill of the National Aviary, 412-258-1148.

p.s. Though many were watching for him, this hummingbird was last seen Sunday morning 4 Nov. He may have moved on.
