Very cool pics. I love hummingbirds, and I'm jealous of folks in the SW corner of the US who have so many amazing and beautiful species to enjoy. Up in my neck of the woods, there is essentially only one species, the Ruby-throated, and they are so aggressive when it comes to defending a food source that the only worthwhile way to feed them is with multiple single-station feeders scattered around the yard. The giant feeders with multi-species clouds of hummingbirds surrounding them are not a thing up here. Two individual birds feeding at once on the same feeder does not happen. They fight constantly.
Now...having said that...will you
please put down that camera...stop screwing around with birds...stop fretting about leeches and filters and who-knows-what...and
finish digging that dang pond!!!!!
