iBird Plus describes the Blue-gray Gnatcatcher’s vocalization as “a distinctive, whining ‘pzzzz’ with a nasal quality”, and that’s exactly how I knew this little fellow was nearby.I was looking the other way when I heard that unmistakable squeaky call. I turned around was treated to the sight of this diminutive Gnatcatcher hopping about in full view!Gnatcatchers are non-stop foragers, and they are known for their “feisty, active mannerisms” (iBird Plus), so they can be quite challenging to photograph. “Flashing the white edges of their long tail may help them flush prey, which they then snap up while the gnatcatcher is perched, hovering, or sallying into the air after them.” (All About Birds – Blue-gray Gnatcatcher). Their diet consists of small insects of all kinds and spiders (Audubon.org – Blue-gray Gnatcatcher).The petite Gnatcatcher is so lightweight he can perch on the edge of a curled leaf. A mere 3-5″ in size, he weighs only about a quarter of an ounce (6 grams)!
