    Accipiters The northern goshawk (Accipiter gentilis) and the sharp-shinned hawk (Accipiter striatus) are the Alaskan representatives of a group of hawks known as accipiters, with short, rounded wings (short in comparison with other hawks) and long tails. The third North American accipiter, the Cooper’s hawk (Accipiter cooperii) is not found in Alaska. Both native species are abundant in the state but not commonly seen, for they spend the majority of their time in wooded habitats. When they do venture out into the open, the accipiters can be recognized easily by their “several flaps and a glide” style of flight. General Description: Adult northern goshawks are bluish- gray on the back, wings, and tail, and pearly gray on the breast and underparts. The dark gray cap is accented by a light gray stripe above the red eye. Like most birds of prey, female goshawks are larger than males. A typical female is 25 inches (65 cm) long, has a wingspread of 45 inches (115 cm) and weighs 2¼ pounds (1020 g) while the average male is 19½ inches (50 cm) in length with a wingspread of 39 inches (100 cm) and weighs 2 pounds (880 g). Adult sharp-shinned hawks have gray backs, wings and tails (males tend to be bluish-gray, while females are browner) with white underparts barred heavily with brownish-orange. They also have red eyes but, unlike goshawks, have no eyestrip. A typical female weighs 6 ounces (170 g), is 13½ inches (35 cm) long with a wingspread of 25 inches (65 cm), while the average male weighs 3½ ounces (100 g), is 10 inches (25 cm) long and has a wingspread of 21 inches (55 cm).

  • Variation in the Procoracoid Foramen in the Accipitridae
    Z6f Riv. Hal. Orn., Milano, 57 (3-4): 161-184, 15-XII-19B7 STORRS L. OLSON (*) VARIATION IN THE PROCORACOID FORAMEN IN THE ACCIPITRIDAE Abstract. — The procoracoid foramen of the eoracoid is present in the great majority of genera of Accipitridae. It may be nearly or completely absent in indivi- duals of Circus and Harpagus, the taxonomic significance of which is uncertain. The procoracoid foramen is invariably absent in the genus Accipiter, although the con- dition is still unknown in Erythrotriorchis and Megatriorchis which have sometimes been synonymized with Accipiter. The presence of a well developed procoracoid fo- ramen in Urotriorchis suggests that this genus may not be as closely related to Accipiter as has been assumed. Riassunto. — Variazione nel forame procoracoideo degli Accipitridae. II forame procoracoideo del coraeoide e presente nella maggioranza del generi degli Accipitridi. Esso puo essere quasi o completamente assente in individui di Circus e di Harpagus, fatto dal significato tassonomico incerto. II forame procora- coideo e invariabilmente assente nel genere Accipiter, sebbene tale condizione sia an- cora sconosciuta per i generi Erythrotriorchis e Megatriorchis, a volte posti in sino- nimia con Accipiter. La presenza di un forame procoracoideo ben sviluppato in Uro- triorchis suggerisce che questo genere possa non essere cosi strettamente affine ad Accipiter, come e stato ritenuto. Anatomical characters that may be of use in defining natural sub- divisions of the large and complex family Accipitridae are much to be desired, as, for example, the fused condition of the phalanges of the inner toe (OLSON 1982). Another feature that shows significant variation in the family is the procoracoid process of the eoracoid, the condition of which is worth documenting not just for systematic information but also for purposes of identification of archeological and paleontological materials.

WATSON ThePeregrine Fund, Inc., 566 WestFlying Hawk Lane, Boise,1D 83709 U.S.A. ABSTRACT.--Fromour reviewof articlespublished on diurnal and nocturnal birds of prey occurringin Africa and the western Indian Ocean islands,we found most of the information on their breeding biology comesfrom subtropicalsouthern Africa. The number of published papers from the eastAfrican tropics declined after 1980 while those from subtropicalsouthern Africa increased.Based on our KnoM- edge Rating Scale (KRS), only 6.3% of breeding raptorsin the eastAfrican tropicsand 13.6% of the raptorsof the Indian Ocean islandscan be consideredWell Known,while the majority,60.8% in main- land east Africa and 72.7% in the Indian Ocean islands, are rated Unknown. Human-caused habitat alteration resultingfrom overgrazingby livestockand impactsof cultivationare the main threatsfacing raptors in the east African tropics, while clearing of foreststhrough slash-and-burnmethods is most important in the Indian Ocean islands.We describeconservation recommendations, list priorityspecies for study,and list areasof ecologicalunderstanding that need to be improved.

A PARTIAL POST-JUVENILE MOLT AND TRANSITIONAL PLUMAGE IN THE SHIKRA (ACCIPITER BADIUS) AND GREY FROG HAWK ( A CCIPITER SOLOENSIS) MARC HERREMANS AND MICHEL LOUETTE RoyalMuseum for CentralAfrica, Department Zoology, Leuvensesteenweg 13, B-3080 Tervuren,Belgium ABSTRACT.--Molthas been poorly studied in the Accipitridae. Examination of museum specimens showedthat there are three age-relatedplumages in the Shikra (Accipiterbadius) and Grey Frog Hawk (A. soloensis)similar to the pattern known in the Levant Sparrowhawk(A. brevipes).The juvenile plumage with its distinctively-spottedunderside is replacedby a transitionalpost-juvenile plumage during a partial contour molt between 4-10 mo of age. More feathers on the ventral side than on the dorsal side are replaced during this first contour molt, which is arrested at variousstages of incomplete feather replace- ment. Usually, a significantpart of the ventral pattern changesfrom spotted to barred, whereby the barring is on averagemore prominent than in adults. The early development of a transitional post- juvenile plumage might be related to early sex signaling.The adult plumage replacesthe transitional post-juvenileplumage during a completemolt at about one year of age. In the subspeciesA. b.poliopsis of the Shikra, which has almost no sexual dimorphism in the adult plumage, the transitional plumage is uncommon and very poorly developed.

Ramos2, & José M. Castillo2 1The Peregrine Fund, 566 West Flying Hawk Lane, Boise, Idaho 83709 USA. 2Tikal National Park, Petén, Guatemala C.A. Abstract. We studied Collared Forest-Falcons Micrastur semitorquatus in Tikal National Park, Guatemala from 1988 through 1993, documenting 9 nesting attempts. The Collared Forest-Falcon is a year-round resident, nesting in pre-existing cavities in large trees. Breeding commenced during the middle of the dry season. Egg laying occurred early March to early April, with laying peaking in early March and spanning 30 days (n = 8 clutches), with one exceptionally late laying date in May. The incubation period was 46–48 days at 1 nest and nestlings fledged on average at 50 days of age (n = 5). Only females incubated while males pro- vided food until the mid-nestling period when the females began hunting and delivering prey to the young. Young fledged in June, early in the rainy season and were not observed again at the cavity. Of 16 eggs laid in 8 nests (mean = 2.0), 10 of 16 (63%) hatched, and 8 (80%) of those hatchlings fledged. The only repro- ductive losses resulted from egg depredation (n = 2 nests). The breeding period of the Collared Forest- Falcon lasted approximately 28 weeks from courtship to fledgling dispersal, long in comparison to simi- larly-sized temperate raptors. Accepted 29 June 1999.

  • 2013 the African Raptor Databank Or ARDB Was Launched
    AFRICAN RAPTOR DATABANK first year report: 2013 The African Raptor Databank or ARDB was launched at the 13th PAOC in Arusha, October 2012. The project became possible thanks to the facilitation of The Peregrine Fund and ESRI in supplying important mapping software. A five year period is planned for data gathering to enable comprehensive assessment of the conservation status of each species of African raptor. The project also aims to make use of raptors as ideal indicator species for monitoring the health of African environments. The project depends on the support of raptor biologists, birdwatchers and general enthusiasts in sharing their observations of African raptors. This is a summary of the data gathering exercises during our first year of operation in 2013. Since the last monthly update in early November 2013, there have been a further 1228 records added to the database during December (Tim Wacher: 769; Andre Botha: 297; Joseph Heymans: 162). This brings the database total to 57,547 records (of which 15,607 are historic records captured from the Snow Atlas). The following table displays contributions by country during 2013.

  • Skeletal Studies of the Tropical Hawk Harpagus
    Sept., 1937 BIRD LIFE AT TWENTYNINE PALMS 219 fied through field glasses at close range, near the Inn, long after the migration of the Gambels. On March 3? 1935, an immature bird with definitely dark lores was trapped near the Inn. Gambel Sparrow. Zowotrichiu Zeucophrys gambelii. A winter visitant, present in large flocks. Between February 2 and March 27, 1934, 54 individuals were trapped and banded in variousparts of the oasis. Observations were then interrupted, and the date of emigration was not determined; but Gambel Sparrows were no longer present when trapping was resumed on April 24. Dates of arrival for the fall of 1934 were rather late. A single immature was seen October 23, and 2 or 3 individuals October 30. A small flock was reported at the palms November 17. By February 9, 1935, large flocks were present. In April the song was heard continuously, and the last record is of the song heard in the pasture May 6. Fox Sparrow. Passerella ilium, subsp. November 4, 1935, a Fox Sparrow, of the type with gray head and back, was seen feeding in the drifts of fine dust and leaves about the foundations of the cottages and at the bases of the mesquites. A few moments later it was captured by either a Sharp- shinned or a Cooper hawk. Lincoln Sparrow. Melospize Zincolnii, subsp. Was first identified February 25, 1934. From March 6 to April 26, 18 were banded, many repeating consistently. They were caught in a sparrow trap, placed on a tongue of dry ground beside a sedge-filled pool.

Reynolds Rocky Mountain Forest and Range Experiment Station1 Abstract Availability of nesting sites can limit accipiter populations. Because accipiters nest in dense forest stands, any alteration that opens these stands is likely to lessen their desirability as nest sites. Tree growth and the associated changes in the vegetative structure of aging nest sites limit the number of years sites will be suitable. Therefore, prospective replacement sites should be selected within the core areas of home ranges before precommercial and commercial harvesting begins.
