BEAUTIFUL BLUEBIRD “WING-WAVING!”

Bluebird courtship is as beautiful as is the bird! Last week my daughter Liv joined me on a film scouting mini adventure. She loves learning about wildlife and living in Southern California as she does, Liv is surrounded by beautiful wild creatures and wild lands. We had a fantastic morning of it. Brant Geese, Piping Plovers, Great Egrets, Tree Swallows, and Eastern Bluebirds were just some of the creatures we observed.

The Eastern Bluebirds were especially stunning in the crisp early morning sunshine. One particular gent had not yet secured his partner’s affections. From tree branches adjacent to nesting boxes, he sang softly and flashed his glorious blue wings to a female that had flown in on the scene.

At first we thought he was preening, but no, the bachelor was clearly enticing his lady friend with lapis lazuli flags, gesturing with quick up and down lifting movements. Called wing-waving, these gestures are part of Eastern Bluebird courtship.

The male first sings loudly from treetops. If a female shows interest, he further shows off his skill sets with wing-waving and soft warbles. He then entices her to join him at a nesting box or cavity, he entering first. After he flies out of the box and if all goes well, she enters the cavity, a sure sign the pair are hitting it off!

BLUEBIRD LOVEBIRDS! – DO BLUEBIRDS MATE FOR LIFE?

Love is in the air!

Consistently when out in fields, I see Bluebird pairs that appear strongly committed to each other. I wondered, do Bluebirds mate forever? In our region, we see Eastern Bluebirds. Ornithologists found from a long term study of Western Bluebirds  that the great majority stay together for life. No such studies exist for Eastern Bluebirds however, field observations suggest that about 95 percent mate for life when both are still alive.

Interestingly though, mating for life does not exclude extra pair copulations. Genetic studies of broods show that about twenty percent of nestlings are sired by more than one male.

Pairs softly warble to each other early in the morning, the male brings nesting material to a chosen site, and once she has entered his nesting cavity, she will begin to bring nesting material and he will bring food to her to “seal the deal.” In our north of Boston region, you can see the courtship behavior beginning as early as February and March.

Eastern Bluebirds re-mate with another partner if one dies.

In the photos below, it’s very easy to see the difference between a male and female Bluebird. The female’s blue is a more subdued grayish hue while the male’s blue feathers are brilliantly hued.
