One of them will first land on the beam from which the feeder hangs and give a long and exuberant call, possibly announcing “Feeder’s full again guys, get stuck in”, possibly declaring “My turn now, rack off till I’m done.” They can be rowdy scrappers, these beautiful birds.
Once it's done calling, it will hop down onto the feeder, curl its claws around the bar at the foot of the feeder and then bob its beak into the little feeder hole, take a sip of sweet nectar, then lift its head back up, dart its gaze quickly in each direction, then down for another sip, and on like this for maybe a few seconds, maybe as long as a couple of minutes and then, in a flash, fly off again.
So glad to have these beautiful birds back in our surroundings where once you might go from one year to another without seeing a single one.
