Appears to be a hummingbird nest on a very low branch along a little-used trail near ephemeral water and very large willow.
24 August 2014: Observed several female and male Ruby-throated Hummingbirds (Archilochus colubris) near Cooper Creek at Avondale Park in Denton, Texas.
This is the thumbnail sketch presented by the online North American birds encyclopedia hosted by the Cornell Lab of Ornithology, All About Birds, on the Ruby-throated Hummingbird: "A flash of green and red, the Ruby-throated Hummingbird is eastern North America’s sole breeding hummingbird. These brilliant, tiny, precision-flying creatures glitter like jewels in the full sun, then vanish with a zip toward the next nectar source. Feeders and flower gardens are great ways to attract these birds, and some people turn their yards into buzzing clouds of hummingbirds each summer. Enjoy them while they’re around; by early fall they’re bound for Central America, with many crossing the Gulf of Mexico in a single flight."
Ruby-throated Hummingbirds are an authentic North American bird. In their southernmost range they winter along the coastal reaches of Mexico's southwestern Pacific states and the southern and southeastern states that border on the Gulf of Mexico and the Atlantic closest to Central America whence their farthest wintering grounds are to be found. While most of Central America is home to this native hummer, the Ruby-throated Hummingbird's range does not extend beyond the southern countries of Central America into the South American continent.
To the north, the Ruby-throated Hummingbird's range extends as far north as Canada's midwestern and eastern provinces especially those southern areas therein closest to the border with the United States. The entire eastern half of the United States is home to this native hummer including Texas that provides a land bridge in this tiny bird's annual migration north and south. Only the most western areas of West Texas and the Panhandle are excluded from the Ruby-thorated Hummingbird's range. Equally, Mexico's most northwestern states starting with Chihuahua going west including Sonora, and the two Baja Califronias, Norte and Sur, are outside the range of this busy annual flyer. This jewel of the Western Hemisphere is a North American bird that's a wonder to behold.
Avondale Park is administered by the City of Denton, Texas.
Hummingbirds are birds that constitute the family Trochilidae. They are among the smallest of birds, most species measuring in the 7.5–13 cm (3–5 in) range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm Bee Hummingbird. They hover in mid-air by rapidly flapping their wings 12–80 times per second (depending on the species). They are known as hummingbirds because of the humming sound created by their beating wings, which sometimes sounds like bees or other insects....
