Not yet this spring. The winter hummer left about a month ago. My Carolina Jessamine isn't quite in full bloom, so I don't think it's time. Usually they are early if they get here in time to nectar on the Carolina Jessamine before the blooms are gone.

I haven't seen anything yet. mid to late march is the first I've seen or heard of them up here in the DFW area.

Here is a link that might be useful: the map I usually follow

I've got flowers everywhere, with a few butterflies and bees buzzing in and out of almost every flower...but no hummers

Hummers are smart enough to know it is still winter here....at least, at my house !!!!
