The first known use of gnatcatcher was in 1839
1 I watched the workers so long that I felt quite competent to build a nest myself, till happening to remember that it required gnatcatcher tools.
2 The coastal gnatcatcher has less white in its tail feathers, for example.
3 In 2013, two researchers, Lincoln Carneiro and Alexandre Aleixo recommended recognizing a new species of gnatcatcher, Polioptila attenboroughi, based on an analysis of their morphology, genetics and vocalizations.
4 A federal decision last week to leave the coastal California gnatcatcher on the endangered species list brought praise from environmentalists, but left Southern California developers primed for an ongoing fight.
5 They argued that new research showed that the southern California gnatcatcher is genetically indistinguishable from its Mexican counterparts, and shouldn’t be protected as a separate species.
6 Environmentalists say they would be happy if the gnatcatcher population recovered.
7 The land provides nesting space for the threatened California gnatcatcher, a small, blue-gray songbird, and a rare vernal pool system where fairy shrimp - tiny aquatic crustaceans - are known to thrive.
8 The only nest like the hummingbirds, and comparable to it in neatness and symmetry, is that of the blue-gray gnatcatcher.
9 Other species on the rebound in the isolated dunes include native evening primrose and California gnatcatcher.
10 The group is concerned about several endangered species that would be affected by prototype and actual wall construction, including the checkerspot butterfly, coastal California gnatcatcher and San Diego fairy shrimp.
11 Another familiar bird here, which I never met with in the North, is the gnatcatcher, called by Audubon the blue-gray flycatching warbler.
12 “And the gnatcatcher and many other species are threatened as a result of that habitat loss. How many pieces of the engine can you remove until the engine breaks down?”
13 All told, people spotted more than 80 different avian species munching on the insects, from large trumpeter swans to teeny-tiny blue-gray gnatcatchers.
14 Another familiar bird here, which I never met with in the North, is the gnatcatcher, called by Audubon the blue-gray fly-catching warbler.
15 “The gnatcatcher listing was absolutely critical not just to ensure the survival of that one species, but also to set the wheels turning on these regional habitat conservation plans,” Hogan said.
16 Its developers are targeting coastal homeowners and “move-down buyers” from affluent parts of Southern California, but they’re also aiming to attract one resident in particular: the California gnatcatcher.
17 “Back then, there were virtually zero measures in place anywhere in Southern California to protect the gnatcatcher or its critically endangered habitat,” Hogan said.
18 And the gnatcatcher was at the center of it.
19 Martha’s Vineyard: Nineteen snow geese at the Vineyard Golf Club in Edgartown, a marbled godwit at Eel Pond in Edgartown, and a blue-gray gnatcatcher on Clay Pit Road at Aquinnah.
20 At that time, a 20-year-old environmentalist named David Hogan with the Center for Biological Diversity filed a petition to list the gnatcatcher under the Endangered Species Act.
