Beak of the Week - Yellow-billed Cuckoo

Yellow-billed Cuckoo
(Coccyzus americanus)
Family: Cuculidae

Spring migration is often synonymous with the arrival of flashy yellow birds flitting through the treetops. But the Yellow-billed Cuckoo - our Beak of the Week - has only a little bit of yellow to add to the mix.

Yellow-billed Cuckoos appear slender and clean-cut, with their upperparts brown and undersides white. They have long tails with white spots underneath, their wings have patches of reddish-brown, and – you guessed it – they have yellowish bills.

Despite being comparable in size to Blue Jays, Yellow-billed Cuckoos are often hard to spot as they move sneakily and quietly through the treetops looking for insects to eat. They feed primarily on caterpillars, which many other species of insectivorous birds will avoid, but they will also catch other insects in flight.

When their food sources are particularly abundant, nesting Yellow-billed Cuckoos will occasionally lay an egg in a nearby nest belonging to another tree-nesting species, such as American Robin, letting the nest owners take care of feeding and raising their young.

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...
