This study sought to assess the concentrations of heavy metals in the feathers of avian species and in soils using X-ray fluorescence in Barangay Ipil-Calancan Bay, Sta. Cruz, Marinduque Island, Philippines. Iron, Cu, Zn, Mn, Cr, Sc, Pb, Sr, and Se were observed in all samples while Co and As were only found in sampled avian species. Among these heavy metals, the concentrations of As, Cr, Pb, Se, and Zn were beyond the critical levels which were reported in other studies. Highly significant concentrations of Cr, Cu, Fe, Sc, Sr, Zn, and Mn were observed in Philippine pied fantail, white browed crake, white-collared kingfisher and little heron. Arsenic accumulation was only observed in yellow-vented bulbul while Cu, Fe, Sr, Zn, and Cr were significantly lowest in pink- necked green pigeon and Tabon scrubfowl.

    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.

    The Philippines Small Group Tour Endangered Endemics th th 10 March to 30 March 2021 (21 days) Philippine Eagle by Rich Lindie Composed of 7,107 islands strewn across a vast stretch of tropical sea, the Philippines occupy the unenviable position of harbouring the most birds facing imminent extinction. Many of these critically endangered yet spectacular species survive only in increasingly shrinking remnants of habitat. During our tour, we can expect to encounter close to 150 endemic birds and many other spectacular migrants RBL The Philippines – Endemics Itinerary 2 and residents. Our Endangered Endemics tour explores the Philippines’ three largest islands. On Luzon, we visit sites for Stripe-headed Rhabdornis, Scale-feathered Malkoha, the sensational Yellow-breasted Fruit Dove, secretive Whiskered Pitta and recently discovered Chocolate Boobook. Mindanao hosts the largest tracts of remaining lowland forest and here we search for the secretive Wattled Broadbill, Azure- breasted Pitta and beautiful Philippine Trogon. The forested slopes of Mt. Kitanglad are the most reliable site for the magnificent Philippine (Monkey-eating) Eagle, this giant raptor is often rated as the world’s single-most desirable bird! Here we will also search for another recently discovered bird, Bukidnon Woodcock, as well as Apo Myna and Giant Scops Owl. On Palawan, white sandy beaches, extensive coral reefs and an underground river make a spectacular backdrop for a number of the specials we are likely to find. Highlights include the mound-building Philippine Megapode, Red-bellied and Hooded Pittas, the incredibly beautiful Blue Paradise Flycatcher and glittering Palawan Peacock-Pheasant.

Villegas2 and Maria Feliza Janet M. Oquendo3 1Philippines Biodiversity Conservation Foundation Inc., Bacolod City, Philippines 2 Aquos Foundation Inc., Puerco Island, Roxas, Palawan 3Cuixmala, Jalisco, Mexico *Correspondence: [email protected] ABSTRACT We documented a total of 53 species of birds on Puerco Island from May 2016 to December 2019 using a combination of modified area search method and photo-documentation. The number of birds increased from only 15 species in 2014 to 53 in December 2019. Records included two endangered species, 18 migratory and 28 native birds. Monthly monitoring of Barred Rail Hypotaenidia torquata, Olive-backed Sunbird Cinnyris jugularis and Collared Kingfisher Todiramphus chloris showed varying levels of abundance. Nest monitoring of the Near- threatened Philippine Scrubfowl Megapodius cumingii cumingii, locally called “tabon”, using close circuit television cameras, showed a significant increase from only three nests reported in 2012 to 154 in September 2019. The changes in the species composition and the increase in the breeding population of Philippine Scrubfowl are attributed to the integration of conservation management strategies on Puerco Island. Keywords: Endangered, Megapodius, Tabon INTRODUCTION The Philippines is an archipelago made up of 7,641 islands with 722 known birds of which 254 are endemic to the country (Allen 2020). The list of species is likely to increase to more than 722 as new records are added (Allen 2020). The revisions in taxonomy elevated a number of subspecies to species level thereby contributing to the increase in the number of endemic birds to 254 (Campbell et al.

  • Philippines: Island Archipelago Endemics (Including Sierra Madre Expedition)
    Philippines: Island archipelago endemics (including Sierra Madre expedition). Custom Tour: 8 – 30 April 2012 Mindanao Wattled Broadbill. Birds, anywhere in the world, don’t come much finer than this. www.tropicalbirding.com Tour Leaders: Keith Barnes and Mark Villa Photos: Nick Athanas, Sam Woods and Keith Barnes Introduction: With our Asian office in neighbouring Taiwan, the Philippines is becoming an increasingly popular destination for Tropical Birding and we ran two different custom tours to the islands in March and April 2012, this trip report covers one of these tours. This tour took the form of three distinct stages, concentrating on the three most accessible, endemic rich islands in the sprawling Philippine archipelago, that encompasses more than 7,000 islands in total. We began first on Mindanao, the second largest and most southerly of the main islands, that is especially noteworthy for birders as the last stronghold of the Philippine National Bird, the magnificent Philippine Eagle; we then hit the 'main' island of Luzon and managed a special expedition to the tough to reach forests of the Sierra Madre mountains. Luzon is the largest of all the islands and where the bustling capital Manila is located; finally we ventured to the thin tropical island strip of Palawan, that sits between the Sulu Sea to the east and the South China Sea to the west, dividing this paradise island from the huge island of Borneo farther west. Biogeographically Palawan is very interesting, sharing more in common with the typically southeast Asian avifauna of Borneo to the west than the other Philippine islands to the east.

(Pete Morris) CLASSIC PHILIPPINES 20 JANUARY – 11 FEBRUARY 2019 LEADERS: PETE MORRIS and JULIEN MAZENAUER Having operated a long series of successful Philippines tours over the last three decades it was once again time to reorganize the tours. With so much to see in the Philippines we decided to return once again to the two tour strategy, with this tour and the Remote Philippines which concentrates on some of the smaller islands and their associated endemics. This, our Classic Philippines tour, cherry picks its way around the three main islands of Luzon, Mindanao and Palawan, scoring heavily on both numbers of endemics and the proportion of ‘signature’ birds seen. As such, it is the recommended 1 BirdQuest Tour Report: Classic Philippines 2019 www.birdquest-tours.com The nightbirding was fantastic as typifed by this brilliant Philippine Frogmouth at Mt Kitanglad (Pete Morris) tour for those only intending to visit this fascinating archipelago once. Sadly, habitat destruction continues at pace in this already critically-threatened country; a visit sooner rather than later is rec- ommended! During our more-or-less three weeks, we recorded a grand total of just under 340 species, a good to- tal for the tour, and more importantly we scored a high proportion of the ‘diamond’ birds - those highly desired species. Some of those iconic birds that we drooled over included the must-see Philippine Eagle, Palawan Peacock-Pheasant and Azure-breasted Pitta. Our success rate with the endemic targets overall was very good indeed, and special mention on this tour should go to the 12 species of owl seen (including Philippine Eagle-Owls near to Manila and impressive Giant Scops Owls), the amazing Flame-breasted Fruit-Dove, 11 stunning species of kingfshers and three gorgeous species of pitta.

Tour Summary Located in Southeast Asia, the Republic of the Philippines is an archipelago between the South China and Philippine Seas composed of 7,107 islands strewn across a great stretch of tropical waters. The Philippines occupies the unenviable position as the number one most critically at-risk destination in the world for endemic plants, animals, and birds followed by Madagascar and eastern Brazil, respectively. RBT The Philippines May 2007 3 Having led tours through each of these ecologically devastated countries, I can bear witness that nothing compares to the imminent degradation of the Philippines. Because of unregulated logging, a massive farming expansion, and migrating lowland populations, this modern disaster has only continued to escalate. Our tour began in Manila on the island of Luzon where we weaved our way through the hustle of the city crowd and shiny decorated taxi buses called jeepneys out of the city to the University town of Los Banos. We first successfully located the smart Indigo-banded Kingfisher along a forested stream followed by sightings of the localized Lowland White-eye.

    GAZETTEER AND SITE-BASED HISTORY OF THE ORNITHOLOGY OF SABAH, MALAYSIAN BORNEO FREDERICK H. SHELDON OCCASIONAL PAPERS MUSEUM OF NATURAL SCIENCE LOUISIANA STATE UNIVERSITY, NO. 86 Baton Rouge, October, 2015 GAZETTEER AND SITE-BASED HISTORY OF THE ORNITHOLOGY OF SABAH, MALAYSIAN BORNEO FREDERICK H. SHELDON Museum of Natural Science and Department of Biological Sciences, Louisiana State University, 119 Foster Hall, Baton Rouge, LA 70803, USA E-mail: [email protected] ABSTRACT The gazetteer lists sites in the state of Sabah, Malaysia, where birds have been collected, studied, or watched. Its purpose is to identify locations for research and birding in Sabah and to provide a brief scientific history of the more important sites. Each site description includes latitude, longitude, and general information on location. For many sites, elevation, habitat, scientific or birdwatching importance, historical notes, citations of key papers, specimen records, and records of certain species are also included. Key words: Birds, Birdwatching, Borneo, Georeference, History, Research, Scientific collecting INTRODUCTION The Malaysian state of Sabah, formerly known as British North Borneo, has a rich ornithological history extending back to the first publication on its birds by Motley and Dillwyn (1855). This gazetteer provides a view of that history by listing and characterizing sites where ornithologists have collected and studied birds and where birders have watched them. The gazetter is a revised version of one that was included in Sheldon et al. (2001). It corrects mistakes in the original version by taking advantage of the development of new methods for finding and georeferencing localities (e.g., Google Earth, online gazetteers, and GPS devices).
