Descriptive notes.Israeli population somewhat intermediate between nominate race and pekinensis. Large rakish swift with long, deeply forked tail and sharply pointed wings. 16-19 cm, 25-50 g, wingspan 42-47 cm.Black-brown mantle, outer wing, lesser coverts, tail, crown and underparts beneath small off-white throat patch. Slightly paler inner wing, greater coverts of underwing, forehead and rump. contrast between paler and darker tracts varies individually and temporally, fresh feathers being blacker with narrow white fringes. Race pekinensis has paler forehead and shows greater contrast in wing. Habitat.Occurs over all habitats, from arid steppe and desert, temperate zones to boreal zone. from sea-level to high altitude.Race pekinensis occurs in Hmalayas at 1500-3300 m. Abundance in Britain and Ireland seemingly correlates with climate. In Israel primarily in Mediterranean climatic zone, with only small numbers in semi-desert areas. Food and FeedingInsectivorous. Mainly hemiptera (55%), with stinging insects avoided.Breeding.Mar-Jun, in Israel, May-Jun in Pakistan and Kashmir, May-Jul in Britain and Ireland, Switzerland and Fenno-Scandia.Site prospected and chosen by male, initially female greeted with hostile display, though allopreening occurs when she submits by lifting aead to expose throat patch. Copulation on wing and at nest. Nest cup constructed of small pieces of vegetable matter and feathers, agglutinated with saliva. 2 eggs, incubation 19-20 days. Movements.Present at SW Palearctic sites from Mar, arriving later farther N. Main arrival N Europe early May, with migration persisting to early Jun.Main spring and autumn passage in Egypt late Mar to mid May. Spring migration of nominate race through Israel mid Jan to mid Jan, peaking Apr-May, passage S throughout country May-Nov. In spring pekinensis moves mainly in Mar-Apr. Leaves N Europe from lat Jul. Autumn movement over W Turkish migration watchpoints peaks Ags. Present on African wintering grounds from Sep. Broad front autumn migration from Europe on SSW bearing, returning by generally more E route. Status and ConservationNot globally threatened. Populatin estimates in 1997, 4.000.000 pairs.Israel.In Israel two subspecies A. a. apus A. a. pekinensis. Rare passage migrant over all the country, and scarce in spring in Eilat area. |
