Bird Fact Friday – Weekly Warbler: Blackburnian

Blackburnian Warbler, Spring Male, credit Scott Whittle

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.

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.

Bird Fact Friday – The most loquacious geese

From page 235 in Waterfowl of North America, Europe, and Asia:

A snow goose can be very loquacious, even noisy, especially in flight, when taking off or landing. It produces loud, raucous, barking calls gwok or ga-ik, as well as other sounds more like those of grey geese, lower and hoarser: gung, wa-iir or hun-hrr. Large flocks utter these calls continuously and at different pitches, linked to the birds’ size.

Color plates and photos are accompanied by informative captions and 85 distribution maps are also provided. Taken together, this is an unrivaled, must-have reference for any birder with an interest in the world’s waterfowl.

Bird Fact Friday – When habitat dictates behavior

From page 15 of Better Birding:

Habitat very often dictates behavior. A Northern Harrier glides and swoops low over fields and marshes, periodically flapping and hovering. It behaves this way because it hunts rodents and this kind of low, cruising flight allows it to more easily detect prey. A Harrier’s long wings allow it to pluck rodents cleanly from grassy cover. Harriers have evolved just so, to nimbly take advantage of these open habitats, including during migration. An appreciation of these qualities allows good birders to recognize a Harrier by its structure or movements from considerable distances. Species evolve to take best advantage of their environment.

Bird Fact Friday – Why do birds molt?

From page 32 in The Crossley ID Guide: Eastern Birds:

Birds essentially do the same things cyclically, and this includes molting. They do this for a number of reasons. It is important that feathers be kept in good condition to keep the bird warm, dry, and mobile. Of course, some like to look good to attract a mate! Having an understanding of molt and how it affects a bird’s appearance is a large help not only in identifying birds but also in ageing and sexing them.

These beautiful compositions show how a bird’s appearance changes with distance, and give equal emphasis to characteristics experts use to identify birds: size, structure and shape, behavior, probability, and color. Each scene provides a wealth of detailed visual information that invites and rewards careful study, but the most important identification features can be grasped instantly by anyone.

Bird Fact Friday – How to identify birds in various light conditions

From page 5 in Hawks from Every Angle:

Understanding how various light conditions can affect the appearance of raptors is important in identification. Lightly colored birds can lack contrast and appear uniformly dark in poor light, such as when backlit or against a cloudy sky, whereas true dark morph birds show a contrast underneath between the body and flight feathers. By contrast, birds can look paler than usual when illuminated by highly reflective ground cover such as snow, sand, and pale grasses. Several conditions affect the way a bird’s size and shape are perceived. Against a bright blue sky, birds often appear smaller than usual; however, birds may appear larger than usual when observed against cloud cover.

Bird Fact Friday — Not so bird brained after all…

From page 161 of Bird Brain:

Bird Brain
An Exploration of Avian Intelligence
Nathan Emery
With a foreword by Frans de Waal
Introduction

EmeryBirds have not been known for their high IQs, which is why a person of questionable intelligence is sometimes called a “birdbrain.” Yet in the past two decades, the study of avian intelligence has witnessed dramatic advances. From a time when birds were seen as simple instinct machines responding only to stimuli in their external worlds, we now know that some birds have complex internal worlds as well. This beautifully illustrated book provides an engaging exploration of the avian mind, revealing how science is exploding one of the most widespread myths about our feathered friends—and changing the way we think about intelligence in other animals as well.

Bird Brain looks at the structures and functions of the avian brain, and describes the extraordinary behaviors that different types of avian intelligence give rise to. It offers insights into crows, jays, magpies, and other corvids—the “masterminds” of the avian world—as well as parrots and some less-studied species from around the world. This lively and accessible book shows how birds have sophisticated brains with abilities previously thought to be uniquely human, such as mental time travel, self-recognition, empathy, problem solving, imagination, and insight.

Written by a leading expert and featuring a foreword by Frans de Waal, renowned for his work on animal intelligence, Bird Brain shines critical new light on the mental lives of birds.

Bird Fact Friday – The bird in the mirror

From page 138 of Bird Brain:

Mirrors have been used in experiments with birds to test if they have a sense of self. Different species of birds react in different ways when confronted with their reflection. For example, flamingos will only mate when their flock is large enough—mirrors have been used to trick them into thinking it is. Various crows behave as if in the presence of another bird, with females preening and males displaying. New Caledonian crows use the mirror to forage for food that is not visible without it, suggesting that they know how it works. Magpies seem to recognize their own reflection, and use the mirror to preen parts of their bodies that were not visible without the mirror.
