WorldTwitch 4 - 1993

For a review of new species of birds described from 1981 to 1990, see Vuilleumier et al., Bull. B.O.C. Centenary Volume 112A:267-309 (1992).

Morocco: 28 Northern Bald Ibis, Geronticus eremita, were observed about 8 km north of Tamri in April, 1993. (D. Bradford)

Congo: Maned Owls, Jubula lettii, have been found to occur in high densities of up to 16 pairs/km² in permanently and seasonally flooded forest in southwestern Congo. Vocalizations are described in detail by Françoise Dowsett-Lemaire at Bull. B.O.C. 112:213-218 (1992). [See "A comment on the voice and status of Vermiculated Fishing-Owl, Scotopelia bouvieri, and a correction to Dowsett-Lemaire (1992) on the Maned Owl, Jubula lettii." Dowsett-Lemaire F. pp 134-135. Bull. African Bird Club 3.2 (1996).]

Kenya: Friedmann's Lark, Mirafra pulpa, a little-known species, was found in numbers in Tsavo West National Park in December 1992. 55 calling birds were counted in two successive mornings, and the observers (D. Pearson, S. Rodwell and D. Turner) estimated that 150 males were present. Pearson et al. believe that "it should be possible to separate Friedmann's at close range from the local race (marginata) of Singing Bush Lark by its generally warm brown (as opposed to drab or greyish brown) upperparts and more sharply streaked mantle. Also, its bill appears rather heavier, the pale supercilium less pronounced and the crest (at least when calling) more emphasized." Kenya Birds 1(2):43-44 (1992).

Tanzania: In August 1992, a team of Cambridge University students caught and released what appeared to be a rufous-phase Sokoke Scops Owl, Otus ireneae, in the lowland forests of the Usambaras, a major range extension of a bird formerly believed to be confined to Cymometra forest on the Kenya coast. Kenya Birds 1(2):34 (1992).

Uganda: Kenya Birds, 1(2):34, reports that two mangled specimens prepared as part of a training course in field techniques have been identified as Grey Ground Thrushes, Zoothera princei. The birds were trapped in Semliki Forest during August 1992.

Sri Lanka: At least five calling Ceylon Spurfowl, Galloperdix bicalcarata, were present on the morning of 30 December 1992 in disturbed forest patches, 10 minutes by foot from Kudawa Base Camp along the short cut to Weddagala. (N.J. Gardner).

Tibet: A new species of mountain finch, Leucosticte sillemi, has been described from two specimens collected in 1929 at 5,125 m in western Tibet. The skins were found in a mixed drawer of Montifringilla and Leucosticte in the collection of the Zoological Museum of Amsterdam. (C.S. Roselaar, Bull B.O.C. 112:225-231 (1992)).

China: A new species, the Hainan Leaf Warbler, Phylloscopus hainanus, has been discovered on Hainan Island, where it apparently is endemic. In plumage patterns and vocalizations it resembles the White-tailed Leaf Warbler, P.davisoni, but it is bright yellow, like the Sulphur-breasted Warbler, P.ricketti.  (U. Olsson, et al., Ibis 135:2-7 (1993)(includes fine color photographs of hand-held individual)).

Mexico: In April 1993, two pairs of White-throated Jays, Cyanolyca mirabilis, were found in second-growth pine-oak forest along a logging track running west from the Puerto Ángel Road about 25 km north of La Soledad, Oaxaca, and at least two pairs of Yellow-headed Parrots, Amazona oratrix, were observed in thorn forest at Km 233 on the coastal highway west of Pinotepa Nacional, Oaxaca. (J.W. Wall & D.E. Sargeant).

Guatemala: In December 1992, Richard Waldrop heard an Unspotted Saw-whet Owl, Aegolius ridgwayi, calling on several consecutive nights, and eventually saw the bird in the canopy of a tall cedar near Km 33 on the road from Guatemala City to Antigua. He also reports that Horned Guan, Oreophasis derbianus, is fairly common in cloud forest above the village of El Cimiento, Dept. El Progresso.

Costa Rica: Two different parties of birders have been robbed at gunpoint recently at the parking area along the main highway through Braulio Carillo National Park. In addition, visitors report that the Costa Rican police repeatedly stop rental cars to solicit bribes and that unattended cars are broken into throughout the country.

Ecuador: Spot-fronted Swift, Cypseloides cherriei, not previously known from Ecuador, was found nesting near a waterfall at Las Palmeras (1,900 m) near Chiraboga between April and June during the 1989-1992 seasons, and a bird was collected at the same place on 26 August 1990. (M. Marín A. et al., Condor 95:479-483 (1993)).
