Beak of the Week - Rusty Blackbird

Rusty Blackbird (Euphagus carolinus)

Family: Icteridae

Rusty Blackbirds have been the talk of High Island for the last few weeks, as they are currently being seen in Smith Oaks Sanctuary for the first time. They winter in the Eastern United States and are relatively uncommon in Southern Texas.

These birds have a thin, curved bill and a shorter tail than Common Grackles. Breeding males have the glossy black plumage that is characteristic of Icterids. Nonbreeding males, however, have black or dark brown feathers with rusty edging. A black mask surrounds their pale iris, bordered above by a pale supercilium. Females look similar to nonbreeding males but are lighter overall with a gray rump.

They prefer wooded swamps and pond edges, where they forage on the ground for insects and seeds, often wading through water and flipping over leaves. Rusty Blackbirds form small flocks and may associate with Red-winged Blackbirds and Common Grackles during the nonbreeding season. In the breeding season, they select a wet area to build their nests in the boreal forests of Canada and Alaska.

Unfortunately, Rusty Blackbirds are experiencing an extremely steep decline, with the population approximately 85-99% of what it was 40 years ago (according to the 2014 State of the Birds Report). Although we are not sure what is causing this, it is thought that wetland drainage, deforestation, climate change, and mercury poisoning may be involved. If you want to see these beautiful and vulnerable birds up close, be sure to stop by Smith Oaks Bird Sanctuary soon.

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...
