Payne (1983) considered this a common summer resident Common Moorhen, Florida Gallinule, and south of the Saginaw Bay area, and especially Black Gallinule, is a chicken-like member of the plentiful in the St. Clair Flats and the Lake Erie rail family (Rallidae). This quiet, skittish, yet marshes. However, this species has declined in graceful relative of the American Coot prefers Michigan in recent years probably due to human permanent marshes with dense, emergent disturbance and habitat degradation (Brewer et vegetation (Kleen et al. 2004).

Breeding Biology Conservation Needs Common Gallinules return to Michigan from Common Gallinule populations depend on the mid-March to late April (MNFI 2007). protection and proper management of marshland Common Gallinules are more aquatic than true habitat.

  • Coyote Reservoir & Harvey Bear..…
    Coyote Reservoir & Harvey Bear..…. February 24, south Santa Clara County Quick Overview – Watching the weather reports we all saw the storm coming, but a group of adventurous souls arrived with all their rain gear and ready to go regardless of the elements, and what a day we had! Once east of Gilroy and traveling through the country roads we realized that soaking wet birds create unique ID challenges. With characteristic feathers in disarray and the wet plumages now appearing much darker we had to leave some questionable birds off our list. We had wanted to walk some of the trails that make up the new Harvey Bear Ranch Park, but the rain had us doing most of our birding from the cars which was easy along Coyote Reservoir Road as it parallels the lake. It also makes it easy when no one else is in the park. We could stop anywhere we wanted and we were not in anyone’s way – a birder’s dream come true! Watching Violet Green Swallows by the hundreds reminded us all that spring is near. And at one stop we got four woodpecker species. Ending our day watching Bald Eagles grasp fish at the surface of the water was worth our getting all wet! And I’ll not soon forget our close encounter with the dam’s Rufous Crowned Sparrow. Since we started our day at the south entrance of the park we ended Rufous Crowned Sparrow our day at the north entrance. It was here we listened to above and hard working Western Meadowlarks and watched a Say’s Phoebe.

  • A Classification of the Rallidae
    A CLASSIFICATION OF THE RALLIDAE STARRY L. OLSON HE family Rallidae, containing over 150 living or recently extinct species T and having one of the widest distributions of any family of terrestrial vertebrates, has, in proportion to its size and interest, received less study than perhaps any other major group of birds. The only two attempts at a classifi- cation of all of the recent rallid genera are those of Sharpe (1894) and Peters (1934). Although each of these lists has some merit, neither is satisfactory in reflecting relationships between the genera and both often separate closely related groups. In the past, no attempt has been made to identify the more primitive members of the Rallidae or to illuminate evolutionary trends in the family. Lists almost invariably begin with the genus Rdus which is actually one of the most specialized genera of the family and does not represent an ancestral or primitive stock. One of the difficulties of rallid taxonomy arises from the relative homo- geneity of the family, rails for the most part being rather generalized birds with few groups having morphological modifications that clearly define them. As a consequence, particularly well-marked genera have been elevated to subfamily rank on the basis of characters that in more diverse families would not be considered as significant. Another weakness of former classifications of the family arose from what Mayr (194933) referred to as the “instability of the morphology of rails.” This “instability of morphology,” while seeming to belie what I have just said about homogeneity, refers only to the characteristics associated with flightlessness-a condition that appears with great regularity in island rails and which has evolved many times.

  • Blue-Winged and Green-Winged Teals, Are the Marshes, Swamps, and Ponds of Zero to Low Water Movement
    BirdWalk Newsletter 1.29.2017 Walk Conducted by: Perry Nugent Newsletter Written by: Jayne J. Matney Photo right by Cary McDonald Blue-winged Teal male with duckweed beak and chest followed by female partner Photo below by Chuck Fuhrman Two Green-winged Teal males This week will be the first in a series of articles covering the ducks of Magnolia Plantation. Most of our duck population is not of permanent residences. Instead, they migrate in for wintering and migrate out for breeding. The males are called “drakes” and the females are called “hens”. Some of these ducks are considered “dabblers”, which means they eat primarily along the surface of the water chewing or filtering from the surface and rarely dive, while others are the “divers”, which do just that-they dive head first into the water for feeding. Dabbling ducks will occasionally dive for food or to escape predators. Photo above left by Chuck Fuhrman Blue-winged Teal Photo above right by Perry Nugent Green-winged Teal The Blue-winged Teal, Anas discors, (above left) and the Green-winged Teal, Anas crecca, (above right) will be discussed this week. They are in the category of dabblers; both species primarily feed off of aquatic plants and seeds from the surface of the water and small larvae, insects, and crustaceans that may be found there as well. Apparently, egg laying females may feed mostly on animal rather than plant during those special times. Both species are small comparatively to other types of ducks, rest out of the water on stumps, rocks and broken branches, and are fast in flight.

The form that occurs in the NACC area is nominate pacificus, so the current species account would remain unchanged except for the distributional statement and notes. Background: The Fork-tailed Swift Apus pacificus was until recently (e.g., Chantler 1999, 2000) considered to consist of four subspecies: pacificus, kanoi, cooki, and leuconyx. Nominate pacificus is highly migratory, breeding from Siberia south to northern China and Japan, and wintering in Australia, Indonesia, and Malaysia. The other subspecies are either residents or short distance migrants: kanoi, which breeds from Taiwan west to SE Tibet and appears to winter as far south as southeast Asia.

    irds find Maine attractive for many of the same reasons we do—the state offers a unique blend of landscapes spanning from mountains to the sea, with forests, grasslands, rivers, marshes, and long coastlines in between. B Where we find beautiful places to hike and kayak, camp and relax, birds find the habitat they need for their survival. But while Maine’s diverse habitats serve an important role for over IBAs 400 bird species—some threatened, endangered, or of regional conservation in concern—the state’s not immune to a growing list of threats that puts these birds at further risk. Habitat loss, degradation, and fragmentation due to development, toxins such as mercury and lead, oil spills on the coast and Maine inland waters, and climate change are top among them. BY ANDREW COLVIN In the face of these threats, a crucial step in conserving Maine’s birds is to identify the areas of the state that are most important for breeding, wintering, and migration. After several years of working toward that goal, Maine Audubon Lists Maine Audubon has recently completed the first phase of its Important 22 of the Most Important Bird Areas (IBA) program, identifying 22 areas across Maine that are vital Places in Maine for Vulnerable Birds to state—and even global—bird populations.

My feathers are a bright white, but my eyes are a piercing yellow. I like water, so I live in marshes, ponds, shores, and mudflats. Great Blue Heron I am a member of the Heron family. I have grayish-blue feathers, long legs and a large wingspan. My s-shaped neck makes me look hunched over. I’m adaptable and can live in marshes, swamps, shores and tide flats. Ruddy Duck I am recognizable by my bright blue bill! Females have brown bills. You can often find me in the water, diving for my food. I also have brown feathers, a black cap and white cheeks. I live in freshwater marshes, ponds and lakes. American Wigeon I am a member of the ducks and geese family. I have a pale blue beak, and a white crown on top of my brown speckled feathers.
