Birds on a Wire: Vesper Sparrow 25 Oct 2016, 2:55 pm

The Vesper Sparrow population has been in decline in the Eastern U.S. due to habitat loss. It is still common in the West however.

It prefers meadows, prairies, and fields. It is most easily seen along dirt back country roads. 

The Vesper Sparrow forages on the ground looking for insects and seeds. It will eat beetles, grasshoppers, caterpillars and moths. Seeds are of weeds and grasses. 

This photo was taken in San Rafael Valley east of Patagonia.

Birds on a Wire: Vermillion Flycatcher 23 Oct 2016, 4:52 am

The Vermillion Flycatcher is a stunningly beautiful bird. Although it's range is limited in the US to Southern Arizona and Southwest Texas, it is fairly easily seen due to its bright red color. 

It prefers streamsides in arid country, savanna, ranches and riparian areas. It usually perches on leafless tree branches over streams (like a Phoebe) or on wires/fences near open grassy areas where there would be plenty of beetles, flies, wasps, and grasshoppers.

In looking through my photos for this post, I realized that I didn't have a good photo of a male Vermillion Flycatcher on a Wire. So, I included a male which was perched on a rail.

Birds on a Wire: Tropical Kingbird 21 Oct 2016, 4:42 am

The Tropical Kingbird is widespread throughout the American Tropics rarely coming into the US and primarily Southern Arizona when it does so. Unlike the other Kingbirds (Western, Cassin's, Thick-Billed) they are generally solitary and avoid large flocks.

It usually perches on wires and fences sallying out to capture insects in flight. It will also hover and drop to the ground to pick up insects.

Birds on a Wire: Swainson's Hawk 19 Oct 2016, 4:36 am

The Swainson's Hawk is a Western United States raptor whose population unfortunately is in decline.  It can easily be mistaken for a Red Tailed Hawk, especially in its juvenile stages. Like the Red Tailed it uses telephone poles as perches, but unlike Red Tails, it prefers insects to rodents, snakes, and other birds (though it will occasionally take those animals, especially in the early summer). It hunts from its perch, by soaring over grasslands, and by running around on the ground.

Birds on a Wire: Scissor Tailed Flycatcher 17 Oct 2016, 4:28 am

Many flycatchers like wires too. It provides them with visibility and a perch to "snatch" insects that fly by. They'll sit on telephone wires, but also fence posts and barbed wires.

The Scissor Tailed Flycatcher is no exception. The STF prefers open country such as ranches, farms, or desert grasslands with scattered trees. It's range is essentially Texas in the summer and the tropics in the winter with occasional reaches into Southern Arizona during those summer months. It can be more easily found along the road where there are telephone poles/lines and fences.

Birds on a Wire: Red Tailed Hawk 15 Oct 2016, 4:19 am

Raptors in particular love telephone poles. They provided great visibility, a perch for taking off after a  "meal," and a stand for creating a nest.

Southern Arizona has some great raptor corridors. Sulphur Springs Valley south of Willcox; along the Santa Cruz River near Tubac; and Santa Cruz Flats west of Picacho Peak are three major areas in Southern Arizona. It is not unusual to find over 100 raptors in any of these three locations at certain times of the year.

Red Tailed Hawks are the most common hawk throughout much of North America. I remember reading somewhere years ago that if you see a hawk, there is a 90% chance it is a Red Tailed Hawk. I don't know if that is statistically true, but certainly it is the most abundant raptor.

The Red Tailed Hawk is also the most variable in plumage. As such, you don't always recognize it immediately as a Red Tailed. The plumage is especially variable west of the Mississippi where it could be near black to nearly white -- and all shades in between. As an adult the distinguishing characteristic is the "red" -- more like "orange" tail. However, in juvenile stages the tail is much lighter complicating identification further.

Birds on a Wire: Prairie Falcon 13 Oct 2016, 5:29 am

Another beautiful raptor is the Prairie Falcon.

Like the Peregrine Falcon the Prairie Falcon was also decimated by pesticides during the mid 1900's. Unlike the faster Peregrine Falcon, the Prairie Falcon pursues smaller prey by flying close to the ground. It likes small birds and mammals.  It's habitat preference is plains and flat scrub desert.

Birds on a Wire: Peregrine Falcon 11 Oct 2016, 5:22 am

The Peregrine Falcon is a beautiful raptor built for speed. They catch medium sized birds, including waterfowl, in the air with swift, spectacular dives called stoops.

The population of Peregrine Falcons was significantly reduced by pesticides during the mid 1900's. After controls of pesticides were initiated, Peregrines were reintroduced in temperate areas throughout the United States with success. The result has been the recovery of Arctic nesting populations as well.

Birds on a Wire: Mountain Bluebird 9 Oct 2016, 5:13 am

Next in the series of Birds on a Wire we come to the Mountain Bluebird. 

Mountain Bluebirds are fairly common in the Western United States. They can be found year round in Northern Arizona, with occasional winter sightings in Southern Arizona. Their preferred habits are prairies and sagebrush, as well as alpine tundra. They like wide open spaces where they hunt insects from perches. Thus wire provide the perfect "perch."

Birds on a Wire: Merlin 7 Oct 2016, 5:05 am

The Merlin is a small falcon about the size of the more abundant Kestrel. The Merlin winters in the Southwest and summers in Canada, while the Kestrel stays year round in the Southwest. The Merlin is most often seen (in Arizona) -- as the photo below suggests -- sitting on fence posts in desert grasslands. It feeds almost exclusively on small birds --- specifically the grassland sparrows.
