Tree Swallows are now turning up in Sam Smith Park to claim nesting boxes. This cold looking group of early arrivals was photographed by Peter Wade last week in a tree close to the park’s Swallow Field (immediately east of the yacht club).
One
reason that Tree Swallows are able to return so early and get their nests built
and eggs laid before the other swallows return is that they don’t go that far
south for the winter, staying in Mexico and Central America as well as
the Caribbean, but not venturing very far into South America. The Barn Swallow, for example, winters as far south as the southernmost
tip of South America.
Unlike other swallow species, Tree Swallows can eat plant foods (berries and seeds) as well as catching their normal insect prey on the wing. This helps them survive the cold snaps and wintry weather of early spring. It is estimated that 20% of their diet is plant material.


If you notice some boxes missing from last year’s locations, it is
because we are in the process of moving most of them to the Swallow Field. The swallows prefer open nesting areas and
are not as stressed if their boxes are away from shrubbery and there is
appropriate space between them. We intend
to install another ten boxes in the Swallow Field after they are built this May
at the Spring Bird Festival.
Did you know that we have four species of swallows that breed in the park - Tree Swallows, Barn Swallows, Cliff Swallows and Rough Winged Swallows?
