The Missing Anna's Hummingbirds

Anna's Hummingbird

Anna's Hummingbird

We live in the Sacramento region and the past several years have had Anna's year-round; the only breed from what I read that are here all year.


This spring some Black Chin Hummers showed up and within a couple of weeks, the Anna's disappeared!

It is now July and for certain they are gone, but the Black Chin (3 of them) are at the feeders every day.

In fact, they are voracious eaters!

Does this even make any sense?

Why did the Anna's leave?

We obviously like having all hummingbirds here as often as possible, but we miss the Anna's - we hope they come back...

Can you help us understand this mystery?


Hi John

I am not familiar with the behaviour of either of these Hummingbirds as I live in the east and only have Ruby-throated Hummingbirds.

My first thought was that perhaps the Black-chinned Hummers were larger and more aggressive than the Anna's.

I did some research to discover the opposite is true about size differences.

The Anna's Hummingbird is actually slightly larger at 3.9 inches to the Black-chinned Hummingbird at 3.5 inches.

I cannot find any information that confirms my other thought that the Black-chinned Hummingbird is more aggressive.

I know first hand that the Ruby-throated Hummer is tenacious at defending their feeding stations against their own species.

It sounds as though you have more than one feeder out for the Hummingbirds.

If that is the case, I suggest that you move them farther apart from one another and/or setup new ones where they cannot be seen one to another.

I am not sure if this will be the solution, but
it may help.

It is likely that the Anna's have not gone far, they may even be keeping an eye on things but for whatever reason do not like to share your feeders.

It also might be helpful to read this page Hummingbird Feeder Wars!

I would also suggest that you could join a Hummingbird Facebook group and ask there.

There must be others who host both these types of Hummers at their feeders and perhaps they might be able to shed some light.

I am not sure I have been of any help, but wish you all the best in getting your Anna's back.
