TREE SWALLOWS MASSING

This short film is dedicated a dear friend who recently lost a beloved family member. Along with the tender melody by Jules Massenet, especially the last bits of footage, before the credits, made me think of angels and of hope.

Over the course of the summer while filming the Piping Plover Family at Wingaersheek Beach, Tree Swallows began flocking in ever increasing numbers. They became part of the Piping Plover story not only because a Tree Swallow will occasionally dive bomb a Piping Plover, for whatever reason I am not entirely sure, but also because they are beautiful to observe, and occasionally, seemingly playful, too.

Songbirds that they are, Tree Swallows make a cheery chirping chatter. They have long narrow forked tails, all the better for gliding and for their signature aerial acrobatics. The male’s upper parts are a brilliant iridescent blue-green, the female’s somewhat duller, and both female and male have white underparts. The migrating juveniles are almost entirely brown with either white or pale grayish underparts.tree-swallows-gloucester-massachusetts-11-copyright-kim-smith

Tree Swallows breed in the wetlands and fields of Cape Ann. Their name comes from the species habit of nesting in tree cavities. Tree Swallows have benefited tremendously from efforts to help save the Eastern Bluebird because they also nest in the nest boxes built specifically for the Bluebirds.

Acrobatic aerialists, they twist and turn mid-flight to capture a wide variety of insects including butterflies, dragonflies, greenheads, bees, beetles, and wasps.tree-swallows-gloucester-massachusetts-copyright-kim-smithTree Swallows eating  insects on the beach and from the crevasses in the driftwood. 

Utilizing both fresh and saltwater to bathe, Tree Swallows have a unique habit of quickly dipping and then shaking off the excess water while flying straight upwards.

Tree Swallows begin migrating southward in July and August. The flocks that we see gathering on Cape Ann migrate along the Atlantic Flyway. They overwinter in the southern states of the U.S., Mexico, the Caribbean, and Central America. Unlike migrating species of butterflies, several generations of Tree Swallows migrate together, the older birds showing the younger birds the way.

    These look and largely behave like the flocks that visit every August. They swirl in a vortex around our home while swarming to devour the ripe bayberries from the bushes. Its a marvel delights me every summer. Am I describing the Tree Swallow or a different Swallow?

    Hi GG Ryan, Tree swallows love bayberies. Unlike other species of swallows (that don’t eat vegetation), vegetable matter makes up about 20 percent of a Tree Swallow’s diet and babyerries are the main plant food. Bayberries grow in sandy soils near seacoasts and Tree swallows are one of the few birds that are able to digest the berry’s waxy coating.
