DANCE OF THE TREE SWALLOWS

Male Tree Swallow

You may have noticed the pretty swallows perching in clusters on telephone lines and flying low over the sand. Both Barn and Tree Swallows can be found at the beach throughout the warmer months, but the birds that are beginning to gather on Cape Ann en masse are the Tree Swallows. The following is a short film from last year’s migration that explains what is happening at this time of year with the Tree Swallows here on our beaches and dunes, and in our neighborhoods.

NEW SHORT FILM: 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-smith

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.
