I'm in SE PA, Brenda, but rarely see any hummingbirds until well into summer. I planted a native honeysuckle last year which seems to be growing nicely on its trellis this spring. Hopefully honeysuckle blossoms will attract some hummers before the bee balm or trumpet vine start blooming. I don't usually put out my hummingbird feeder until I've seen hummingbirds at the blossoms, but perhaps I should reconsider that.
Lucky you to have orioles, too. I've never seen one in my backyard or anywhere else for that matter. I do on occasion put out orange slices (in addition to apple slices which my resident mockingbird loves) but they've failed to attract any birds at all. I'm anxious to make a trip to a local bird sanctuary where last year's spring sightings included included indigo buntings and rose-breasted grosbeaks--both first time sightings for me. I've been lucky enough to get some interesting pics from their bird blind, one of which had the unlikely combination of a deer and hummingbird in the same picture.
Our temperatures dipped into the low 30's overnight and with winds still gusting today it doesn't feel at all like late April. Warmer temps are predicted for the weekend. I'm hoping that the winds and bright sun we've got will help dry out our soggy backyard after all the recent rain we've had the past few days.
