THE KESTREL | September 2019 2 Upcoming Field Trips – compiled by Glen Lindeman Salem Audubon field trips are open to the public, and we usually have a mixture of experienced and novice bird watchers. These trips are a great way to become more familiar with the birds of Oregon, and you will find some great new places to go birding and possibly meet some new friends. There is no fee for the trips, but we do encourage carpooling to try to reduce our impact on the environment, with riders helping to cover the cost of driving. If you have a suggestion for field trips or have any questions, contact Glen Lindeman at (503) 930-1492 or [email protected]. SAS-SHORTS are abbreviated versions of our popular field trips. These trips are in the local area, typically last one to one and a half hours, and cover no more than a mile of walking. They are primarily designed for new birders, although everyone is welcome. Due to their short duration, please arrive before the start time. The outings will begin at precisely the advertised start time. Refer to the outing descriptions below for specifics. Many of our field trips meet at the Airport Road Park and Ride located on the east side of Airport Road, between Mission and State Streets, next to the State Motor Pool and just south of the bridge over Mill Creek. To reach the park and ride, follow Mission Street to Airport Road (the first stoplight east of 25th Street) and turn left. Follow Airport Road north one block to the park and ride. Note that there are no restrooms at this site.

  • American Kestrel, Falco Sparverius
    American Kestrel, Falco sparverius Status: State: Threatened Federal: Not listed Identification The American kestrel is the smallest and most widely distributed falcon in North America (Smallwood & Bird 2002, Hawk Mountain n.d.). At first glance, kestrels are often confused with other small birds such as mourning doves because of their propensity to perch on utility lines (Hawk Mountain n.d.). Kestrels however, have larger more roundish heads and often tip or “bob” their tails while perched. In flight, kestrels have a diagnostic flight pattern of quickly alternating between rapid wing beating and gliding. With proper lighting, their colorful plumage can further aid in positive identification. Kestrels are both sexually dimorphic and dichromatic; therefore sexing can be done at a distance and in chicks as young as three weeks (Hawk Mountain n.d.). Males are on average 10% smaller than females though this may be hard to ascertain in the field (Hawk Mountain 1997, Smallwood & Bird 2002). Males are more colorful, with bluish- gray wings (with or without black barring) and rufous (reddish-brown) tails. A single black bar tipped in white extends across the terminal end of the largely unmarked tail. Females are rufous on their wings and tails, often with multiple black bars extending horizontally along the length (Hawk Male American Kestrel Mountain n.d.). Plumage is highly variable © Jim Gilbert among individuals (Smallwood & Bird 2002). Both sexes exhibit grayish crowns and rufous crown patches with two vertical black stripes down their white cheeks. Black “eyespots on the back of their heads are thought to aid in reducing predation on kestrels by larger birds of prey- giving the illusion of predator awareness.

  • Fascinating Falcons
    48 Fascinating Falcons Falcons, worshipped as the "Lofty Ones," appeared in the writings, paintings, and sculptures of the early Egyptians and Persians some 3,000 years ago. References to the grace and power of falcons appeared during the times of Aristotle and Marco Polo. During the Middle Ages, owning falcons, particularly peregrine falcons, became a symbol of power. Peregrines were sought by kings and other nobility as valuable gifts. Falcons are swift birds of prey found throughout the world, except for a few oceanic islands and Antarctica. The 58 species of the falcon family range in size from the 6.5-inch pygmy falcon of South America to the 25-inch gyrfalcon of the Arctic tundra. The smallest North American falcon is the 9 to 12-inch American kestrel, and the rarest North American falcon is the aplamado falcon. Members of the falcon family have a conspicuous notched bill which is used to break the necks of their prey. Falcons have excellent eyesight. Experiments in Germany confirmed that peregrine falcons can recognize sitting doves from a distance up to 1.5 miles. With high-speed adaptations such as bullet-like heads, short necks, broad shoulders, and long, pointed wings, falcons are among the fastest birds in the world. Peregrines are considered the fastest falcons; they are able to cruise in level flight at 50-60 miles an hour and have been clocked at more than 200 miles per Peregrine Falcon hour in their dives after prey. The peregrine falcon's speed and grace make it one of the most interesting falcons to watch or study.

  • Rock Kestrel
    264 Falconidae: falcons and kestrels brooding young. Therefore the small increase in reporting rates in six of the eight Zones during winter is probably related to seasonal changes in conspicuousness, rather than to any large- scale influx of migrants from outside the region. Reporting rates for the Tarkastad district, for example, increased during winter, while direct observation showed that over half of the population actually left the area (Van Zyl 1994b). Although the models do not suggest movements within southern Africa, a more detailed analysis of Rock Kestrel movements in South Africa, largely based on a more refined examination of atlas reporting rates, suggested a northerly and easterly movement away from south- western breeding areas during winter (Van Zyl et al. 1994). Breeding: Breeding was recorded in all Zones, mainly September–January, peaking October–December. There are no obvious seasonal differences between the Zones, although in the eastern Cape Province (Zone 8) it bred slightly later than in the rest of the region. Interspecific relationships: It overlaps widely with Greater and Lesser Kestrels in southern Africa. It moves into the eastern grassland habitats most exploited by the Lesser Kestrel during the winter when that species is absent (Van Zyl et al. 1994). Historical distribution and conservation: Boshoff et al. (1983) found no difference in distribution in the Cape Prov- ince, comparing the periods 1700–1969 and 1970–79. The distrib- ution map similarly shows no change in distribution, the species being largely absent from the central Kalahari regions and the far northeast during all three time periods, although the map shows Rock Kestrel many more records from the western Karoo, presumably due to Rooivalk better coverage.

  • New Insights Into the Phylogenetics and Population Structure of the Prairie Falcon (Falco Mexicanus) Jacqueline M
    Doyle et al. BMC Genomics (2018) 19:233 https://doi.org/10.1186/s12864-018-4615-z RESEARCH ARTICLE Open Access New insights into the phylogenetics and population structure of the prairie falcon (Falco mexicanus) Jacqueline M. Doyle1,2*, Douglas A. Bell3,4, Peter H. Bloom5, Gavin Emmons6, Amy Fesnock7, Todd E. Katzner8, Larry LaPré9, Kolbe Leonard10, Phillip SanMiguel11, Rick Westerman11 and J. Andrew DeWoody2,12 Abstract Background: Management requires a robust understanding of between- and within-species genetic variability, however such data are still lacking in many species. For example, although multiple population genetics studies of the peregrine falcon (Falco peregrinus) have been conducted, no similar studies have been done of the closely- related prairie falcon (F. mexicanus) and it is unclear how much genetic variation and population structure exists across the species’ range. Furthermore, the phylogenetic relationship of F. mexicanus relative to other falcon species is contested. We utilized a genomics approach (i.e., genome sequencing and assembly followed by single nucleotide polymorphism genotyping) to rapidly address these gaps in knowledge. Results: We sequenced the genome of a single female prairie falcon and generated a 1.17 Gb (gigabases) draft genome assembly. We generated maximum likelihood phylogenetic trees using complete mitochondrial genomes as well as nuclear protein-coding genes. This process provided evidence that F. mexicanus is an outgroup to the clade that includes the peregrine falcon and members of the subgenus Hierofalco. We annotated > 16,000 genes and almost 600,000 high-quality single nucleotide polymorphisms (SNPs) in the nuclear genome, providing the raw material for a SNP assay design featuring > 140 gene-associated markers and a molecular-sexing marker.

  • 1 Systematics and Evolution of Kestrels
    Cambridge University Press 978-1-108-47062-9 — The Kestrel David Costantini , Giacomo Dell'Omo Excerpt More Information 1 Systematics and Evolution of Kestrels 1.1 Chapter Summary The family Falconidae constitutes a group of small to medium-sized diurnal raptors whose monophyly is strongly supported. Kestrels are included in the subfamily Falconinae. There are at least 13 species that belong to the kestrel group, but recent genetic studies suggest that the number of kestrel species might be larger, possibly 16. The paleontological and molecular evidence is congruent in suggesting an evolutionary radiation of kestrels from the Late Miocene (4.0–9.8 million years ago) through the Early Pleistocene. However, the geographic area where kestrels originated and dispersed from is unclear. 1.2 Diversification of Falcons The Falconidae is a monophyletic family of diurnal birds of prey that occupy a wide variety of ecological niches and geographic regions (White et al., 1994). Three subfamilies are currently recognised and their validity is supported by both molecular and morphological data (Griffiths, 1999; Griffiths et al., 2004; Fuchs et al., 2012, 2015): (i) Falconinae (falcons, falconets and kestrels), (ii) Herpetotherinae (forest falcons Micrastur sp. and laughing falcon Herpetotheres cachinnans) and (iii) Polyborinae (caracaras) (Figure 1.1). Dickinson (2003) has recognised 11 genera and 64 species of Falconidae, but figures can vary slightly across authors. Both the Herpetotherinae and the Polyborinae occur only in the New World, while the Falconinae (the subfamily to which kestrels belong) are widespread across both the New and Old World with 46 species, 40 of which belong to the genus Falco (Fuchs et al., 2015).

  • American Kestrel (Falco Sparverius)
    Wildlife Habitat Management Institute American Kestrel (Falco sparverius) April 1999 Fish and Wildlife Habitat Management Leaflet Number 3 General Information The American kestrel is one of the most common and colorful birds of prey in North America. Because of its small size and colorful plumage, it can easily be mistaken for a songbird as it sits atop a utility pole or wire. However, once witnessed hovering over an open field in search of prey, the kestrel’s predatory nature becomes apparent. A member of the falcon family, the American kestrel is closely related to the peregrine falcon and merlin. The bird is often referred to as the sparrow hawk because of its small size. Its scientific name, Falco sparverius, holds the Latin meaning, "falcon of the sparrows." Although its scientific name and the commonly used name "sparrow hawk" imply that the kestrel feeds exclusively on small birds, the majority of the kestrel's diet consists of insects and small mammals. As is the case with many beneficial predator species, the kestrel’s value lies in the role it plays in keeping insect and small rodent populations in check. In the early and mid-1900s, American kestrel populations declined in many parts of North America as a result of the loss of nesting habitat in the form of tree and other natural cavities. A growing human population contributed to the loss of nesting habitat as fencerows and tree-lined field borders were removed to provide crop fields and make way for expanding urbanization. In recent years, the removal of dead standing trees, or snags, for firewood, and the continued clearing of fencerows and hedgerows has had a significant impact on the success of the American kestrel.

  • Kestrel, Also Known As the European Or Eurasian Kestrel, Are One of the Smaller Members of the Falcon Family
    The common kestrel, also known as the European or Eurasian kestrel, are one of the smaller members of the falcon family. They measure just over 30cm in length, and may weigh as little as 150g (5 ½ ounces). They are a native species to Britain, and can be identified by the way they ‘hover’ in place mid-air.
