TREE SWALLOWS
Brilliant flashes of steel blue and white swirled and danced, careened and darted, twisted and dipped in a masterful display of aerial skills.” Sharply bicolored, dark above, clean white below - adults are glossy blue or green above, with a dark cap.

NEST BOX MAINTENANCE
Nest boxes are cleaned out, repaired or replaced and sanitized against parasites before winter. Sometimes we have to evict squatters! The entrance holes are covered until the swallows start arriving in late March the following year. This is done to stop non-migrating, early nesting House Sparrows from claiming the boxes before their arrival. Park visitors are asked not to remove the covers until there are enough swallow pairs in the field to fight off the heavier and more aggressive sparrows.
