A pair of cardinals comes to the deck feeder for sunflower seeds. She sits on the banister and waits. He gets a seed from the feeder and takes it to her on the banister. He strokes her open beak with his in the transfer of the seed. They do this two or three times before flying off together into the neighbor's holly tree across the sideyard fence, where they most certainly have a nest, judging from their frequent entering and exiting of the holly. Though I can't be sure, they are likely the same pair I saw mating in the azaleas last week.
That cardinals mate for life is their most endearing trait, I think, not to mention the brilliant gift of red they offer to anyone paying attention. dkm
