Survey of blood parasites in two forest owls, Northern Saw-whet Owls and Flammulated Owls, of western North America.
The Flammulated Owl (Otus flammeolus) was also reported from El Potosi by Contreras-Balderas (1992b).
Given the high overall ER, this finding suggests marked differences in species susceptibility to the virus, with species falling into one of three groups (for scientific names see Table 1): death rates >90% (Snowy Owl, Great Gray Owl, Northern Hawk Owl, Boreal Owl, and Northern Saw-whet Owl), death rates <20% (Long-eared Owl, Short-eared Owl, Great Horned Owl, Flammulated Owl, and Northern Pygmy Owl), and death rates = 0% (Barn Owl, Burrowing Owl, and Eastern Screech Owl).
Some of the birds that can be found there typically do not occur elsewhere in the country and include the colima warbler, Lucifer hummingbird, band-tailed pigeon, varied bunting, flammulated owl, elf owl, Mexican jay, black-chinned sparrow, green kingfisher, pyrrhuloxia, and crissal thrasher.
Until 13 years ago, little if any research had been done on flammulated owls; just over a century ago the species was unknown to science.
Flammulated Owls (Otus flammeolus) exhibit brood partitioning, the young separating into two groups, each of which is attended by one adult (Linkhart 1984, Goggans 1986, Linkhart and Reynolds 1987).
The dissent argued that the Lightning Ridge sale should not be enjoined because the EA determined that the sale would not harm the habitat of the pileated woodpecker, lynx (Lynz canadensis), wolverine (Gulo gulo), fisher (Martes pennanti pacifica), boreal owl (Aegalius funereus), goshawk (Accipeter gentilis), flammulated owl (Otus flammeolus), or white-headed woodpecker (Picoides albolartus).
The sale not only includes the harvesting of Douglas-firs, but it also brings prescribed burning into the understory that will enhance ponderosa pine and aspen, and create savannah-like stands for specialized species like the flammulated owl.
The Flammulated Flycatcher (Deltarhynchus flammulatus) is a little known, monotypic species endemic to the Mexican Pacific Region.
The seven sensitive species were the lynx, boreal owl, flammulated owl, black-backed woodpecker, fisher, bull charr, and the west-sloped cutthroat trout.
at 757 (9listing the lynx, boreal owl, flammulated owl, black-backed woodpecker, fisher, bull charr, and west-sloped cutthroat trout as species of concern to plaintiffs).
