Age and sex related characteristics of the Loggerhead Shrike
The proliferation of dense herbaceous vegetation could explain the apparent decline in the Island Loggerhead Shrike
(Hicks and Walter 2009), a species that was not detected in my study; sparse herbaceous vegetation has been suggested as providing better foraging habitat for shrikes (Scott and Morrison 1990).
The Santa Clara River valley is one of the last strongholds for loggerhead shrikes
in Los Angeles County.
Relocating foxes from San Clemente Island was preferable to culling foxes in order to protect the loggerhead shrike
for the United States Navy, which owns San Clemente, San Nicholas, and San Miguel Islands.
(Lanius ludovicianus) in South Carolina, USA nested more frequently in red cedar (Juniperus virginiana) trees, which may have more needles than any other species of tree; shrikes in north-central South Carolina that nested in red cedar trees fledged one additional young per nest than shrikes nesting in other types of trees (Gawlik and Bildstein 1990).
The major opposition items are protection of burrowing owl and loggerhead shrike
habitat at two of the three entrances to the school, and many public safety issues caused by a lack of road improvements and infrastructure to protect students and members of Rancho Tierra del Sol,'' Kasper said.
The preserve will protect habitat for several at-risk species, including the zebra-tailed lizard (Callisaurus draconoides), the loggerhead shrike
(Lanius ludovicianus), and rare native plants.
Every single breeding bird observation, whether a common species, such as a robin, mourning dove or house sparrow seen by beginning "backyard" birdwatchers or a real rarity, such as a sandpiper or loggerhead shrike
, documented by an expert and avid birder, will improve the Atlas and measurably add to our knowledge of the occurrence, status and distribution of Pennsylvania's birdlife.
Among those that can be viewed are the blue grossbeak, ash-throated flycatcher and the loggerhead shrike
The objectives of our study were to: (1) ascertain the size and characteristics of Loggerhead Shrike
territories in central Kentucky during the non-breeding season, (2) compare the characteristics of territories used by shrikes during the non-breeding season to those of areas not used by shrikes, and (3) examine the hunting behavior of Loggerhead Shrikes
during the non-breeding season.
The birders became excited when they spotted a turkey vulture and a white-tailed kite, but they were looking for more sensitive species, a common ground dove and a loggerhead shrike
At the eastern edge of the refuge, impaled insects and small rodents adorn the blades of large, 100-year-old yuccas called Spanish daggers (Yucca treculeana), compliments of a migratory bird, the loggerhead shrike
The San Clemente loggerhead shrike
, possibly the most endangered bird in North America, may have a better chance to survive because its landlord, the Navy, is moving to protect the wild population and to breed the shrike in captivity, conservationists say.
Clustered nesting in all-purpose territories has been observed in at least five species of North American songbirds: Yellow Warbler (Dendroica petechia; Clark and Robertson 1979), Henslow's Sparrow (Ammodramus henslowii; Cully and Michaels 2000), Loggerhead Shrike
(Lanius ludovicianus; Etterson 2003), Baird's Sparrow (Ammodramus bairdii; Ahlering et al.
They include the yellow headed blackbird and the American bittern, both found in wetland and riparian areas, and the loggerhead shrike
, which is a perching bird found in open fields and grasslands.
