Beak of the Week - Rufous Hummingbird

Rufous Hummingbird (Selasphorus rufus)

Family: Trochilidae

Hummingbirds are generally known for being quick and energetic fliers, but the Rufous Hummingbird just may be the zippiest of them all. The Rufous Hummingbird is a tiny hummingbird that is very agile in flight, even when compared to other hummingbirds. Despite their small size, Rufous Hummingbirds are particularly territorial, and they are known to aggressively defend their food sources by chasing away other visitors. Their territorial antics can be enjoyable to watch, especially if a Rufous Hummingbird stakes its claim to your hummingbird feeders!

Male Rufous Hummingbirds are the only hummingbirds found in the United States with an entirely orange-colored back. They have a patch of iridescent feathers called a gorget on their throat, which usually appears bright red. Since most hummingbirds appear green at first glance, this bright and shiny coloration makes male Rufous Hummingbirds easy to spot as they zip by from one place to the next. Female Rufous Hummingbirds can be more difficult to identify since they are not quite as alarmingly bright – they are greenish above and buffy white below, but they show characteristic orange coloring in their tail feathers.

The Rufous Hummingbird is commonly found across the western United States, reaching areas of southern Alaska during the summer breeding season. Though they primarily winter in Mexico, some individuals can be reliably found during fall and winter along the Gulf Coast as far east as the Florida panhandle. Rufous Hummingbirds tend to stay close to the Pacific Coast during spring migration, but during fall many will instead stray eastward before heading south, making a large, circuitous journey around the western United States. This fall migration pattern often results in small numbers of Rufous Hummingbirds travelling further east than usual, making them the most common of the “western” hummingbirds in eastern North America.

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...
