Bird Fact Friday – The dancing manakins

From page 166 in The New Neotropical Companion:

Photo by Jill Lapato.

The White-bearded Manakin’s name comes from its throat feathers, which are puffed outward during courtship, forming a kind of beard. Thirty or more males may occupy a lek, a single small area in the forest understory. Each male makes his own “court” by clearing an oval-shaped area of forest floor about 1 m (39 in) across. Each court must contain two or more thin vertical saplings, as these are crucial in the manakin’s courtship dance. The male begins courtship by repeatedly jumping back and forth between the two saplings, making a loud snap with each jump. In addition to the snap, the male’s short wing feathers make an insect-like buzzing when he flies, and thus active manakin leks can become a buzzing, snapping frenzy when a female visits. The intensity of the male’s jumping between saplings increases until he suddenly jumps from sapling to ground, and then appears to ricochet back to another sapling, from which he slides vertically downward, like a fireman on a pole.

Bird Fact Friday – Harris’s Hawks hunt cooperatively

Credit William S. Clark

From page 190-191 in Raptors of Mexico and Central America:

The Harris’s Hawk preys mainly on mammals, especially rabbits, and birds, but also lizards and insects. They hunt on the wing and from perches. Cooperative hunting occurs more often in winter. Unlike many buteos, they don’t hover. They perch more horizontally than other raptors and are often seen in groups of up to a dozen individuals, especially in winter. They breed cooperatively, often with polygamy and nest helpers. A large stick nest is built in small to large trees and sometimes on power poles and cell towers.

Vulture. Adult. Credit William S. Clark

From page 95 in Raptors of Mexico and Central America:

The Lesser Yellow-headed Vultures forage for carrion by gliding low over wet open areas and are able to locate carrion by smell as well as by sight. They also spend lots of time perched on the ground or on a low fence post. Active flight is with slow, deep, deliberate wing beats on flexible wings. They soar and glide with wings in a strong dihedral, often rocking or teetering from side to side, rarely soaring high. Adults’ head color varies with mood; the head is redder when the vulture is excited. Cathartid vultures often bow their wings downward in a flex until the tips almost meet.

Bird Fact Friday – How do long-winged harriers hunt prey?

From page 145 in Raptors of Mexico and Central America:

The Long-winged Harriers are typical harriers that hunt in low, slow flight just above the ground, pouncing on prey with a quick agile strike. They eat small mammals, small birds, frogs, lizards, and bird’s eggs. Some prey is located by hearing, enhanced by their owl-like facial disk. The Long-winged Harrier’s scientific name is Circus buffoniCircus is from the Greek kirkos, “circle,” from its habit of flying in circles. The species name,  buffoni, is for French naturalist George Louis Leclerc, Comte de Buffon.

Bird Fact Friday – Weekly Warbler: Black-throated Blue

From page 192-193 in The Warbler Guide:

Black-throated Blue Warbler, Fall Female, credit Scott Whittle

The female Black-throated Blue Warbler’s blue-green back and buffy undersides create a relatively low-contrast appearance. Its darker cheek creates a faint mask. Though from some angle, the mask can be very prominent. A small white “handkerchief” mark is created by white coloration at the base of the outer primaries. The Black-throated Blue Warbler is an active, understory forager, often seen near eye level. It frequently makes a loud, dry, “kissy” chip call while foraging in the fall. The Black-throated Blue Warbler is a good example of sexual dimorphism: the male and female are very different in color, although their body structure is the same.

From page 254-255 in The Warbler Guide:

The Common Yellowthroat is one of our most widespread warblers. It is wren-like, and often skulks in marsh or low brush near water. It hops when on the ground, and it is frequently seen at or below eye level. The Common Yellowthroat has a small bill, a short neck and overall a plump appearance. It has short, rounded wings and a cocked tail in flight, and it is generally a weak flier. The adult male has a broad black mask across forehead and face, with paler border above, which is unique among warblers. When disturbed, it often pops up quickly, and then dives back down into cover. The Common Yellowthroats are the only U.S. and Canada warblers to nest in open marshes.

From page 166-167 in The Warbler Guide:

The Blackburnian Warbler has fiery orange throat, face, and under-eye arc. Its auricular patch has distinctive triangular shape, pointed at rear and bottom. The Blackburnian Warbler has broad white wing patch, and two pale braces on back unique among warblers. Especially in a dim forest, the bright flash of a Blackburnian can be startling as they sally for insects. Blackburnians nest and are often found high in trees, but color often makes them quickly identifiable. Adult females in spring are not as bright orange as males. The Blackburnian Warbler is a long-distant migrant, and it has relatively long wings.

Bird Fact Friday – Why do birds sing?

From page 18 of Better Birding:

Songs differ from “calls” in that songs are longer, often more complex vocalizations. In most birds (though not all) songs are given by males, usually on the breeding territory, and serve the dual purpose of attracting females and driving away rival males. In some species both males and females sing. When females sing, it is less often about attracting males (though it probably does help strengthen pair bonds) and usually more about territorial defense against neighboring pairs. Often, the species in which females sing are less migratory or resident, so territories require year-round defense from rivals.

Introduction

Better Birding reveals the techniques expert birders use to identify a wide array of bird species in the field—quickly and easily. Featuring hundreds of stunning photos and composite plates throughout, this book simplifies identification by organizing the birds you see into groupings and offering strategies specifically tailored to each group. Skill building focuses not just on traditional elements such as plumage, but also on creating a context around each bird, including habitat, behavior, and taxonomy—parts so integral to every bird’s identity but often glossed over by typical field guides. Critical background information is provided for each group, enabling you to approach bird identification with a wide-angle view, using your eyes, brain, and binoculars more strategically, resulting in a more organized approach to learning birds.

Bird Fact Friday – What’s the best weather for peak hawk flights?

From page 10 in Hawks from Every Angle:

During spring, many peak flights occur ahead of a warm front, as birds heading north use southerly prevailing winds. Most fall flights occur after the passage of a cold front, when northerly winds that assist birds heading south are most prevalent. Geography, however, determines which specific wind directions will lead birds to each site. The most favorable winds for ridge sites are those that strike the ridge at an angle that produces optimal lift. At coastal and shoreline sites, optimal winds are those that “push” birds towards the shorelines. Even during snow squalls or light drizzle, optimal wind conditions can produce significant hawk flights.

How to Identify Raptors In Flight
Jerry Liguori
Foreword by David A. Sibley

Identifying hawks in flight is a tricky business. Across North America, tens of thousands of people gather every spring and fall at more than one thousand known hawk migration sites—from New Jersey’s Cape May to California’s Golden Gate. Yet, as many discover, a standard field guide, with its emphasis on plumage, is often of little help in identifying those raptors soaring, gliding, or flapping far, far away. Hawks from Every Angle takes hawk identification to new heights. It offers a fresh approach that literally looks at the birds from every angle, compares and contrasts deceptively similar species, and provides the pictures (and words) needed for identification in the field. Jerry Liguori pinpoints innovative, field-tested identification traits for each species at the various angles that they are seen.

Featuring 339 striking color photos on 68 color plates and 32 black & white photos, Hawks from Every Angle is unique in presenting a host of meticulously crafted pictures for each of the 19 species it covers in detail—the species most common to migration sites throughout the United States and Canada. All aspects of raptor identification, including plumage, shape, and flight style traits, are discussed. For all birders who follow hawk migration and have found themselves wondering if the raptor in the sky does in fact match the one in the guide, Hawks from Every Angle—distilling an expert’s years of experience for the first time into a comprehensive array of truly useful photos and other pointers for each species—is quite simply a must.
