The grapefruit tree in Dad's backyard was alive with purpley house finches this weekend.
The attraction was a feeder filled with sunflower seeds and the birds wasted no time in stripping the nutritious meats from the shells. When the flock landed, I oozed myself out on to the deck and into a pink plastic chair near the feeder. They fluttered up into the citrus trees chattering and fussing, but I sat still and soon they returned.
The video below shows the basic technique.
