Rough-legged Buzzard Buteo lagopus from Ladakh, India On Sunday, 03 January 2021 I planned a drive towards Hemis village for birding, and while returning via Stakna village (33.97°N, 77.70°E; c.3,230 m) I saw a raptor on a Poplar Poplus nigera. At first I thought it was just another Common BuzzardButeo buteo (first winter), but after taking some photographs and analyzing them I realized that the bird was different from the Common Buzzard we usually see in Ladakh. That evening, I put the photos [48–52] of the bird on social media and sent some photographs for identification to the person I always ask for help in identifying confusing bird species (Andrew Paul Bailey), and to my surprise, everyone commented it was a Rough-legged Buzzard Buteo lagopus! To satisfy myself further, I referred some books I had, Arlott (2014), and Svensson et al. (2010), and was convinced 50. that the bird I had spotted was a Rough-legged Buzzard, which is new for Ladakh. 51. All: Sonam Choldan (Gasha)All: Choldan Sonam 52. 48. 48–52.

The bill is on the electric wire [53]. tiny for other Buteos with feathered tarsi: Long-legged Buzzard B. rufinus and Upland Buzzard B. hemilasius. The tail is extremely important, showing a white inner half and very few sparse and diffuse bars in the dark-shaded outer half; this is a typical tail for a juvenile Rough-legged Buzzard (the uppertail cannot be seen well in the images, but the pattern is clearly shown in some of the backlit images from underneath). Eastern Buzzards (including B. japonicus and B. burmanicus) have brown upper tails and, if there is barring, it is fine, and usually covers the entire upper tail in juveniles. In Upland Buzzard, which is a big and heavy bird, the tail can be partly white, but the barring would be fine and distinct. Most buteos show barred secondaries, with the barring spaced over the entire feather. In juvenile Rough-legged AshDibyendu Buzzard, only the outer section of each secondary shows a few bars, leaving the inner half largely plain white, which is a unique feature as seen in this bird. 53.

Karandinos Abstract: Alivizatos , H., V. Goutner & M. G. Karandinos (1998): Reproduction and behaviour of the Long- legged Buzzard ( Buteo rufinus) in North-eastern Greece. Vogelwarte 39: 176-182. The breeding biology of the Long-legged Buzzard ( Buteo rufinus) was studied in the Evros area, north-eastern Greece in 1989, 1990, 1992 and 1993. The mean number of young fledged per pair per year was similar between years with an overall average of 0.93 (1.58 per successful pair). Of ten home range variables examined, the num­ ber of alternative nest sites and the extent of forest free areas in home ranges were significant predictors of nest­ ling productivity. Aggressive interactions were observed with 18 bird species (of which 12 were raptors), most commonly with the Buzzard {Buteo buteo). Such interactions declined during the course of the season. Prey pro­ visioning to nestlings was greatest in the morning and late in the afternoon declining in the intermediate period. Key words: Buteo rufinus, reproduction, behaviour, Greece.

Gamebirds featured strongly with 14 species seen, the highlights of them including a male Temminck’s Tragopan grazing in the gloom, Chinese Monal trotting across high pastures, White Eared and Blue Eared Pheasants, Lady Amherst’s and Golden Pheasants, Chinese Grouse and Tibetan Partridge. Next were the Parrotbills, with Three-toed, Great and Golden, Grey-hooded and Fulvous charming us, Laughingthrushes included Red-winged, Buffy, Barred, Snowy-cheeked and Plain, we saw more Leaf Warblers than we knew what to do with, and marvelled at the gorgeous colours of Sharpe’s, Pink-rumped, Vinaceous, Three-banded and Red-fronted Rosefinches, the exciting Przevalski’s Finch, the red pulse of Firethroats plus the unreal blue of Grandala.

Well, there was that Red Panda that we watched for ages! 1 BirdQuest Tour Report: Sichuan Including Northern Yunnan 2018 www.birdquest-tours.com Our tour began with a short extension in Yunnan, based in Lijiang city, with the purpose of finding some of the local specialities including the rare White-speckled Laughingthrush, which survives here in small numbers. Once our small group had arrived in the bustling city of Lijiang we began our birding in an area of hills that had clearly been totally cleared of forest in the fairly recent past, with a few trees standing above the hillsides of scrub.

We studied various aspects regarding migration behavior of the Common Buzzard for two subspecies (B. b. buteo and B. b. vulpinus) transiting the region which overlaps with the Western Black Sea Corridor. Using vantage points set across Dobruja we managed to count 2,662 individuals. We highlighted the seasonal and diurnal peak passage, flight directions and height of flight for each season. Our results suggest that 57% of the counted individuals belongs to long-distance migrant Steppe Buzzard - B. b. vulpinus. The peek passage period in autumn migration was reached between the 26th of September to the 6th of October, while for the spring migration peek passage remained uncertain. The main autumn passage direction was from N to S, and NNW to SSE but also from NE to SW. For spring passage the main direction was from S to N but also from ESE to WNW.

  • Winter Presence of Long-Legged Buzzard (Buteo Rufinus) in Moldova (Romania)
    Travaux du Muséum National d’Histoire Naturelle © 28 décembre «Grigore Antipa» Vol. LV (2) pp. 285–290 2012 DOI: 10.2478/v10191-012-0018-6 WINTER PRESENCE OF LONG-LEGGED BUZZARD (BUTEO RUFINUS) IN MOLDOVA (ROMANIA) EMANUEL ȘTEFAN BALTAG, VIOREL POCORA, CONSTANTIN ION, LUCIAN SFÎCĂ Abstract. Long-legged Buzzard (Buteo rufinus) is a medium sized bird of prey which is known as a breeding species for Romania. In the last years it started to become a common wintering presence in the south-eastern part of Romania (Dobrogea) but it was also recorded in the more northern areas (Moldova) during the cold season. Its presence in Moldova, during the winter period, was recorded in large river valleys, with agricultural lands or grasslands and with trees or timber poles, which are used for perching. Long-legged Buzzard is a new presence for Moldavian winter seasons and it could be observed only in warm periods of winter, when the daily mean temperature is above 0°C. The wintering places are maintained not only for all winter period, but also for the next years. This behaviour could be explained by its territorial fidelity, which was recorded also in other European buzzard species during the winter period. Résumé. Buse féroce (Buteo rufinus) est un oiseau de taille moyenne de proie qui est connu comme une espèce nicheuse pour la Roumanie. Dans les dernières années, il est devenu une présence commune au cours de l’hiver au sud-est de la Roumanie (Dobroudja), mais il était également enregistré dans les régions du Nord (Moldavie) pendant la saison froide.

Zoological Museum & Institute of Biodiversity and Ecosystem Dynamics, University of Amsterdam PO Box 94766, 1090 GT Amsterdam, THE NETHERLANDS 2. Department of Biology, Faculty of Science, Ferdowsi University of Mashhad, Mashhad, IRAN * Correspondence Author. Email: [email protected] Received 27 March 2009; accepted 7 October 2009 Abstract: Based on original literature reports covering the period 1860 –1969, details of 362 records of 102 bird species considered rare in Iran are presented. This fills a gap in knowledge of Iran’s birds from a period between research by Gmelin and Hablizl in the 1770s (reviewed by Mlikovsky 2008) and an overview of the observations of rare birds in Iran in the 1960s and 1970s (presented by Scott 2008). Attention is drawn to two new species for Iran (Eastern Marsh Harrier Circus spilonotus and Blue Whistling Thrush Myophonus caeruleus ). Published details validate the records of Light-bellied Brent Goose Branta hrota , Upland Buzzard Buteo hemilasius , Great Knot Calidris tenuirostris , and Oriental Cuckoo Cuculus saturatus , formerly considered as of dubious occurrence in Iran. Information on six species (Yellow-breasted Tit Cyanistes cyanus flavipectus , Falcated Duck Anas falcata , Indian Nightjar Caprimulgus asiaticus , Güldenstädt’s Redstart Phoenicurus erythrogaster , Cirl Bunting Emberiza cirlus and Eurasian Nutcracker Nucifraga caryocatactes) was considered insufficient or unreliable and the occurrence of these species in Iran has been rejected. We recommend that these species be omitted from the last revised checklist of the birds of Iran (Scott & Adhami 2006).
