This is a Blue-headed Vireo, I now know.

Vireos are a hard category for relatively new birders like me. When I got home from my morning walk in Sewall’s Point with camera, I downloaded my photos, saw this one, and Google “warbler white eye ring two wing bars” then looked at the photos that came up. Looked like a Blue-headed Vireo but I thought I would get confirmation from What’s This Bird? on Facebook…

The power of the internet.

So they are not warblers.

Before you start identifying vireos, you need to stop confusing them with other similar families of songbirds.

Florida bird #79 and 2018 bird #49.
