So I'm still trying to understand ruby throat migration and habits....
I sighted my first male at one of my feeders on 4/22. He was there in the morning around breakfast time, but then didn't return. Another male appeared on 4/26- same thing- drank for a minute at a feeder and then flew off not to be seen the rest of the day. This has been happening repeatedly, every day or so, and yesterday morning I saw my first female there in the morning, but she too flew off and I haven't seen her since. They aren't hanging around... I know I can't watch every second, but my feeders are easily seen from my windows and I am home during the day, so I keep a pretty good eye on them. Last year here in VA (and my previous experience out west) a couple of males and females came to the feeders in April/May and stayed in the vicinity, they would return repeatedly during the day to drink and I could follow them to where they were sitting in the trees in the backyard between feedings.
Does anyone know why I'm only seeing birds in the morning? Are they the same birds returning or are they different birds that are passing through? A couple of times I've seen one at lunch time, but that's it. This is only my 2nd hummingbird season here in VA so I'm still trying to understand their habits.
Also, Does anyone know any resources where I can find out specific hummingbird information for my specific area/town? I have been trying to find out if many even migrate through this area/my neighborhood. It's hard to find specific, in depth information...most of the info out there is for people who are beginners or who casually want to attract a hummingbird, as opposed to someone who is really trying to figure out their specific migration habits and behaviors. I found a website called eBird, but it records birdwatching of all kinds and there is hardly any hummingbird data for my county...I don't know if it's because there just aren't many hummers through here or if people just aren't watching for them.
Since you don't provide detail about the habitat surrounding your property it is hard to say much about breeding although your information from last year indicates they likely do breed in your general area.
You could just be seeing migrants since they are moving through now. You also could be seeing local breeders since breeding has started. Females don't usually nest right near an active feeder preferring to be away from persistent male attention. This means that their visits to feeders are sporadic at best because they don't stray too far from their nest. If you have streamside woods nearby it would be a place to look for nesting females.
Generally R-T hummingbirds are pretty common birds although they don't take well to urbanized settings during the breeding season. May can be a slow time at feeders and in gardens and one can't always tell whether there are any hummingbirds are around. You also may not be the only game in town, others may be getting visits who live near you.
