    Abstract Marcot, Bruce G. 1995. Owls of old forests of the world. Gen. Tech. Rep. PNW- GTR-343. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 64 p. A review of literature on habitat associations of owls of the world revealed that about 83 species of owls among 18 genera are known or suspected to be closely asso- ciated with old forests. Old forest is defined as old-growth or undisturbed forests, typically with dense canopies. The 83 owl species include 70 tropical and 13 tem- perate forms. Specific habitat associations have been studied for only 12 species (7 tropical and 5 temperate), whereas about 71 species (63 tropical and 8 temperate) remain mostly unstudied. Some 26 species (31 percent of all owls known or sus- pected to be associated with old forests in the tropics) are entirely or mostly restricted to tropical islands. Threats to old-forest owls, particularly the island forms, include conversion of old upland forests, use of pesticides, loss of riparian gallery forests, and loss of trees with cavities for nests or roosts. Conservation of old-forest owls should include (1) studies and inventories of habitat associations, particularly for little-studied tropical and insular species; (2) protection of specific, existing temperate and tropical old-forest tracts; and (3) studies to determine if reforestation and vege- tation manipulation can restore or maintain habitat conditions. An appendix describes vocalizations of all species of Strix and the related genus Ciccaba. Keywords: Owls, old growth, old-growth forest, late-successional forests, spotted owl, owl calls, owl conservation, tropical forests, literature review.

    CLP Report Assessment and conservation of threatened bird species at Laojunshan, Sichuan, China Submitted by Jie Wang Institute of Zoology, Chinese Academy of Sciences, Beijing, P.R.China E-mail:[email protected] To Conservation Leadership Programme, UK Contents 1. Summary 2. Study area 3. Avian fauna and conservation status of threatened bird species 4. Habitat analysis 5. Ecological assessment and community education 6. Outputs 7. Main references 8. Acknowledgements 1. Summary Laojunshan Nature Reserve is located at Yibin city, Sichuan province, south China. It belongs to eastern part of Liangshan mountains and is among the twenty-five hotspots of global biodiversity conservation. The local virgin alpine subtropical deciduous forests are abundant, which are actually rare at the same latitudes and harbor a tremendous diversity of plant and animal species. It is listed as a Global 200 ecoregion (WWF), an Important Bird Area (No. CN205), and an Endemic Bird Area (No. D14) (Stattersfield, et al . 1998). However, as a nature reserve newly built in 1999, it is only county-level and has no financial support from the central government. Especially, it is quite lack of scientific research, for example, the avifauna still remains unexplored except for some observations from bird watchers. Furthermore, the local community is extremely poor and facing modern development pressures, unmanaged human activities might seriously disturb the local ecosystem. We conducted our project from April to June 2007, funded by Conservation Leadership Programme. Two fieldwork strategies were used: “En bloc-Assessment” to produce an avifauna census and ecological assessments; "Special Survey" to assess the conservation status of some threatened endemic bird species.

    The bizarre-looking Philippine Frogmouth. Check those eyes! (Dani Lopez-Velasco). ULTIMATE PHILIPPINES 14 JANUARY – 4/10/17 FEBRUARY 2017 LEADER: DANI LOPEZ-VELASCO This year´s Birdquest “Ultimate Philippines” tour comprised of the main tour and two post-tour extensions, resulting in a five-week endemics bonanza. The first three weeks focused on the better-known islands of Luzon, Palawan and Mindanao, and here we had cracking views of some of those mind-blowing, world´s must-see birds, including Philippine Eagle, Palawan Peacock-Pheasant, Wattled Broadbill and Azure- breasted Pitta, amongst many other endemics. The first extension took us to the central Visayas where exciting endemics such as the stunning Yellow-faced Flameback, the endangered Negros Striped Babbler or the recently described Cebu Hawk-Owl were seen well, and we finished with a trip to Mindoro and remote Northern Luzon, where Scarlet-collared Flowerpecker and Whiskered Pitta delighted us. 1 BirdQuest Tour Report: Ultimate Philippines www.birdquest-tours.com Our success rate with the endemics– the ones you come to the Philippines for- was overall very good, and highlights included no less than 14 species of owl recorded, including superb views of Luzon Scops Owl, 12 species of beautiful kingfishers, including Hombron´s (Blue-capped Wood) and Spotted Wood, 5 endemic racket-tails and 9 species of woodpeckers, including all 5 flamebacks. The once almost impossible Philippine Eagle-Owl showed brilliantly near Manila, odd looking Philippine and Palawan Frogmouths gave the best possible views, impressive Rufous and Writhed Hornbills (amongst 8 species of endemic hornbills) delighted us, and both Scale-feathered and Rough-crested (Red-c) Malkohas proved easy to see.

However, comparisons between the material from Strix seloputo and our own material from Strix aluco, the type host of H. syrnii, revealed morphological and molecular differences. H. ilanpapernai n. sp. differs morphologically from H. syrnii by the much smaller size of the gametocytes, the different position of the mature gametocytes in the erythrocyte (apical, subapical, or lateral in H. ilanpapernai vs. always lateral in H. syrnii), the effect on the erythrocyte nucleus (frequently tilted in H.

This study examined and quantitatively described the territorial calls and duets of the Sunda Scops-Owl (Otus lempiji), Brown Boobook (Ninox scutulata) and Spotted Wood-Owl (Strix seloputo) based on 105 territorial call and four duetting recordings collected from one forest reserve and oil palm smallholdings in Selangor, Peninsular Malaysia. Wilcoxon signed-rank tests found significant differences p( <0.05) for almost all vocal parameters measured from the spectrograms derived from the duets with one higher-pitched than the other. Being the first study to describe the vocal structure of the duetting calls of the three Malaysian strigids, this study serves as a baseline for future behavioural study of nocturnal birds particularly pertaining to conspecific interactions in the Sunda region.

    Pig pipeline 9CTV[ - BEKI Updates - Face to face with the warty pigs! The Bawean deer (Axis kuhlii) The Bawean deer is endemic to Bawean island. Although historically the deer were also found on Java, they became extinct, most likely due to competition with two other species, the Javan rusa and the southern red muntjak. In the last decades, the Bawean deers’ numbers have shrunk to about 250-300 animals due to deforestation, conversion of forest into teak plantations, and uncontrolled hunting. Numbers are reported to be stable but there has not been a systematic survey. Bawean deer seem to prefer secondary forest with dense undergrowth where they can rest in hiding during the day. They feed on herbs and grasses, young leaves and twigs. The animals sometimes enter Group of Bawean warty pigs (August 2015, photo: openings and croplands in search for food.

  • Old Conifer Forests of North America
    Old Conifer Forests of North America 1. Ancient forest of western hemlock (Tsuga heterophylla) and western redcedar (Thuja plicata), Olympic National Park, western Olympic Peninsula, Washington. Such stands are habitat for the Northern Spotted Owl (Strix occidentalis caurina) but in recent years also have been invaded by the Barred Owl (Strix varia). The Barred Owl is fast becoming coexistent with, and in many cases replacing, the less aggressive Spotted Owl. 2. Fragmentation of western hemlock forests in southeast Alaska, Tongass National Forest, from timber harvesting (clearcutting). Such harvesting locally opens forest canopies and eliminates habitat for Boreal (Tengmalm’s) Owls (Aegolius funereus) and other species. 3. Selective cutting of western hemlock forests in southeast Alaska. If such cutting does not greatly reduce canopy closure or nesting substrate (including snags and cavity-bearing trees), then it may be compatible with conserving habitat for some of the old-forest owl species. Studies are needed, however, to assess the response of each species. Hume and Boyer (1991) and Amadon and Bull (1988) list the Lesser Sooty Owl, previously considered a subspecies of the Sooty Owl, as a separate species. Hume and Boyer note that both species inhabit patches of rain forest and wet eucalyptus forests containing old trees with hollow trunks suitable for nesting and roosting, and that the Lesser Sooty Owl favors extensive tracts of rain forests. Both owls have recently taken to roadsides and clearings as foraging habitat, however. 5 Soumagne’s Owl-Soumagne’s Owl is found only in large, dense, evergreen forests of northeastern Madagascar. It has been sighted only in 1929 and 1973 (Clark and others 1978).

    malaysia: the peninsula custom tour July 29 – August 4, 2014 Tour Leader: Scott Watson Report and Photos by Scott Watson Like a Sunbird on steroids, the very common, Streaked Spiderhunter. Introduction: This custom tour was designed to maximize the number of Peninsular Malaysian specialties, in only 7 days time, and birding at only 2 locations. Both Fraser’s Hill and Taman Negara national Park are 2 perfect locations for this short custom tour. By visiting these two sites we covered both hill forest and lowland forest zones, thereby maximizing the best species this peninsula has to offer. We saw some great gems such as; Garnet Pitta, Malaysian Rail-Babbler, Malayan Whistling-Thrush, Great Argus, Malayan Peacock-Pheasant, Diard’s Trogon, Rhinocerous Hornbill, lots of Woodpeckers, Bulbuls, and Babblers, and a great selection of Broadbills. All in all we saw an amazing 233 species of birds and 11 species of mammals, not bad for a 7 day (5 birding day) tour! We stayed at 2 fantastic lodges, both with good food and cold beer, and drove on paved roads for the entire trip! Peninsular Malaysia offers up a great duo of easy travel and some of the best birding in Southeast Asia. Itinerary: July 29 Kuala Lumpur arrival to Fraser’s Hill July 30 Fraser’s Hill July 31 Fraser’s Hill to Taman Negara National Park August 1 Taman Negara National Park August 2 Taman Negara National Park August 3 Taman Negara National Park August 4 Taman Negara National Park to Kuala Lumpur departure The bulky Fire-tufted Barbet is always a favourite.

  • Egg Laying Behavior of Common Cuckoos (Cuculus Canorus): Data Based on Field Video-Recordings
    ZOOLOGICAL RESEARCH Egg laying behavior of common cuckoos (Cuculus canorus): Data based on field video-recordings DEAR EDITOR, terms of time, some parasites, such as common cuckoos, are The egg laying behavior of brood parasites is at the heart of known to lay their eggs in the afternoon or evening (Nakamura studies on host co-evolution. Therefore, research on egg et al., 2005; Wyllie, 1981). As hosts lay eggs and stay close to laying behavior can improve our understanding of brood the nest in the morning, but rarely in the afternoon, afternoon parasitism and associated processes. Over a seven year parasitism reduces the risk of detection by the host and the study period, we monitored 455 oriental reed warbler possibility of parasitic egg rejection (Davies & de L. Brooke, (Acrocephalus orientalis) nests during the egg laying period, 1988). However, some parasites such as cowbirds (Molothrus 250 of which were parasitized by common cuckoos (Cuculus spp.) complete egg laying before sunrise (Gloag et al., 2013; canorus). We collected 53 clear videos of common cuckoo Sealy, 1992). The entire process of egg laying by a brood parasitism, analyzed all recorded parasitic behavior in detail, parasite is usually short (less than 10 s) (Davies & de L. and summarized the process of brood parasitism. Brooke, 1988; Ellisson et al., 2020; Moksnes et al., 2000; Furthermore, based on analyses of the field video recordings, Scardamaglia et al., 2017; Soler & Soler, 2000); despite this, we propose a new explanation for egg removal behavior, in addition to egg laying, brood parasites also display other namely the delivery hypothesis, i.e., egg pecking and biting by complex behaviors.
