Beak of the Week - Brown-headed Nuthatch

Brown-headed Nuthatch
(Sitta pusilla)
Family: Sittidae

Often found clinging to tree trunks and branches, the Brown-headed Nuthatch is equally at home climbing upward and downward among the high branches of pine forests. Their rather unique habit of walking down tree trunks headfirst may appear silly, but it comes in handy when they are foraging for insects in the deep crevices of pine bark or gathering seeds from within pine cones.

The Brown-headed Nuthatch appears large-billed, short-legged, and short-tailed, especially for a bird that’s only 4 ½ inches long. It has a dark bluish-gray back and is white below, with a brown cap on the top of its head. Flocks of Brown-headed Nuthatches are most often heard before they are seen, their repetitive squeaky calls sounding like rubber ducks high in the treetops. Though Brown-headed Nuthatches are usually seen in small groups throughout the year, they occasionally join mixed-species flocks with chickadees and woodpeckers during the winter months.

During the breeding season, Brown-headed Nuthatch pairs will excavate a hole in a tree in which to build their nest. These nest holes are usually between 5 and 15 feet above the ground, but they will also make use of birdhouses and existing holes from old woodpecker nests when available. Though the female will typically remain on the nest to incubate their eggs and rely on the male to bring her food, some nesting pairs are known have an additional “helper” male that also brings food to the female and young in the nest.

How to DIY a Dripper for birds

Are you running out of home projects to keep busy during the quarantine? Here’s one my hubby made for me that you can try: a DYI Dripper. I’ve long wanted a bird dripper to complement my yard’s wildlife habitat, and with spring migrants on the way, I was keen to provide a drip that will attract new birds that don’t visit feeders. I had a problem though. There is no water line or power source near my feeders. The idea of stringing a hose or wire across the driveway just isn’t practical. Enter the engineer. My husband thought about the location and the limitations for a bit, and came up with the concept of sourcing water for a dripper off the sprinkler system. By using a toilet tank that fills every time the sprinklers run, water can be constantly available for the drip. I nixed the idea of a toilet tank sitting in my yard though, so he made some aesthetic modifications by installing a toilet tank float inside a 5 gallon bucket hidden inside a custom wooden box with a handsome copper p

Beak of the Week - Yellow-crowned Night-Heron

Yellow-crowned Night-Heron ( Nyctanassa violacea ) Family: Ardeidae Our Beak of the Week is the official Bird of Houston , the Yellow-crowned Night-Heron! This seemingly hunch-backed bird can be a difficult one to spot. Both species of North American night-herons, yellow-crowned and black-crowned, forage mainly at night and spend most of the day hidden among branches near a body of water. These two birds can be differentiated easily by their plumage on and around their head. The most obvious difference is stated in their names: Yellow-crowned Night-Herons have a yellow crown and Black-crowned Night-Herons have a black crown. But that’s not the only difference! Yellow-crowned Night-Herons have a black head and face with a distinct thick white cheek stripe, whereas Black-crowned Night-Herons have a black head with gray on their face that extends down the whole front of the body. Yellow-crowned Night Herons also have a gray front and neck, but it contrasts greatly with their facial patter

Beak of the Week - Ruby-throated Hummingbird

Ruby-throated Hummingbird ( Archilochus colubris ) Family: Trochilidae Did you know that Ruby-throated Hummingbirds are able to fly in all 6 directions with wing beats of 53 times per a second? Ruby-throated Hummingbirds are bright emerald or golden-green on the back and crown with gray-white underparts. Males have a brilliant iridescent red throat while females and immatures have fine, dark throat streaking. Ruby-throated Hummingbirds feed on the nectar of red or orange tubular flowers as well as at hummingbird feeders and sometimes tree sap. Hummingbirds also catch insects in midair or pull them out of spider webs. In preparation for their migration, Ruby-throated Hummingbirds double their weight from 3 grams to over 6 grams prior to departing. In the fall, millions of Ruby-throated Hummingbirds will pass through Texas on their migration to points south of the border with many crossing the Gulf of Mexico in a single flight. They arrive from breeding grounds as far away as Nova Scotia
