MFF: Bird Couples ATC

Lately I've been noticing images/pictures of bird couples. Is it nesting time? Are they COMMITTED couples, or do they choose a new partner each year? These are things I don't know about many bird varieties. I know that swans, for instance, mate for life, but robins? No idea. At any rate, I love seeing the sweet couples of the few varieties of birds out and about in the cold January weather. Let's make an ATC featuring a bird couple. Any bird couple...swans, cardinals, other little birds whose names I don't know...the choice is yours!
