Pelecanus Onocrotalus Pelecanus onocrotalus -- Linnaeus, 1758 ANIMALIA -- CHORDATA -- AVES -- PELECANIFORMES -- PELECANIDAE Common names: Great White Pelican; Pélican blanc; White Pelican European Red List Assessment European Red List Status LC -- Least Concern, (IUCN version 3.1) Assessment Information Year published: 2015 Date assessed: 2015-03-31 Assessor(s): BirdLife International Reviewer(s): Symes, A. Compiler(s): Ashpole, J., Burfield, I., Ieronymidou, C., Pople, R., Tarzia, M., Wheatley, H. & Wright, L. Assessment Rationale European regional assessment: Least Concern (LC) EU27 regional assessment: Least Concern (LC) At both European and EU27 scales this species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 10% in ten years or three generations, or with a specified population structure). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern within both Europe and the EU27. Occurrence Countries/Territories of Occurrence Native: Albania; Armenia; Azerbaijan; Bosnia and Herzegovina; Bulgaria; Cyprus; Georgia; Greece; Hungary; Italy; Macedonia, the former Yugoslav Republic of; Montenegro; Romania; Russian Federation; Serbia; Turkey; Ukraine Vagrant: Austria; Belarus; Croatia; Czech Republic; Denmark; Finland; France; Latvia; Malta; Netherlands; Norway; Poland; Portugal; Slovenia; Spain; Switzerland Population The European population is estimated at 4,900-5,600 pairs, which equates to 9,700-11,100 mature individuals. The population in the EU27 is estimated at 4,400-4,800 pairs, which equates to 8,800-9,700 mature individuals. For details of national estimates, see Supplementary PDF. Trend In Europe and the EU27 the population size is estimated to be increasing. For details of national estimates, see Supplementary PDF. Habitats and Ecology Its regular habitat includes fresh or brackish water of lakes, deltas, lagoons and marshes, often requiring extensive reed beds for breeding. Within Europe the populations are fully migratory (Elliott et al. 2014) and travel via important stop-over sites (Nelson 2005). The species is entirely piscivorous, and in Europe it prefers carp (Cyprinus carpio) (Elliott et al. 2014) Habitats & Altitude Habitat (level 1 - level 2) Importance Occurrence Marine Intertidal - Mud Flats and Salt Flats suitable breeding Marine Neritic - Macroalgal/Kelp suitable breeding Marine Neritic - Seagrass (Submerged) suitable breeding Habitats & Altitude Habitat (level 1 - level 2) Importance Occurrence Marine Neritic - Subtidal Loose Rock/pebble/gravel suitable breeding Marine Neritic - Subtidal Rock and Rocky Reefs suitable breeding Marine Neritic - Subtidal Sandy suitable breeding Marine Neritic - Subtidal Sandy-Mud suitable breeding Wetlands (inland) - Bogs, Marshes, Swamps, Fens, Peatlands suitable breeding Wetlands (inland) - Permanent Saline, Brackish or Alkaline Marshes/Pools major breeding Wetlands (inland) - Permanent Saline, Brackish or Alkaline Marshes/Pools major non-breeding Altitude max. 1370 m Occasional altitudinal limits Threats The species is threatened by habitat destruction through drainage (Crivelli et al. 1991, Johnsgard 1993, Nelson 2005, Elliott et al. 2014), the divergence of rivers for irrigation (Johnsgard 1993), agriculture development and industry (Elliott et al. 2014). It is also subject to climatic fluctuations that have a strong influence over water-levels in wetlands: floods leading to the inundation of nesting sites (Elliott et al. 2014) and lowering water-levels leading to the death of fish due to increased water salinity (Crivelli 1994). The species is threatened by persecution (Johnsgard 1993, Elliott et al. 2014) and hunting for sport because of its (minimal) depredation of fish from fish-farms (Crivelli et al. 1991, Kostadinova et al. 2007). It also suffers mortality due to collisions with electric powerlines during migration, dispersal or on its wintering grounds and is often found drowned in fishing nets (Crivelli et al. 1991). Disturbance (Elliott et al. 2014), (e.g., from tourism) threatens breeding colonies (Crivelli et al. 1991), and pesticides, heavy metal contamination and disease could have devastating effects on large colonies in the future (Crivelli et al. 1991, Elliott et al. 2014).

It occurs within 43 Important Bird Areas. Within the EU it is listed within 108 Special Protection Areas. Conservation Actions Proposed Monitoring and review of water management practices in key habitats. Protection of breeding and feeding sites. Enforcement and monitoring of persecution, including educational programmes to reduce this threat. Monitoring of heavy metal and pesticide levels, and improved management of water bodies to reduce contaminant loads. Bibliography Crivelli, A.J., Leshem, Y, Mitchev, T. and Jerrentrup, H. 1991.

  • Tube-Nosed Seabirds) Unique Characteristics
    PELAGIC SEABIRDS OF THE CALIFORNIA CURRENT SYSTEM & CORDELL BANK NATIONAL MARINE SANCTUARY Written by Carol A. Keiper August, 2008 Cordell Bank National Marine Sanctuary protects an area of 529 square miles in one of the most productive offshore regions in North America. The sanctuary is located approximately 43 nautical miles northwest of the Golden Gate Bridge, and San Francisco California. The prominent feature of the Sanctuary is a submerged granite bank 4.5 miles wide and 9.5 miles long, which lay submerged 115 feet below the ocean’s surface. This unique undersea topography, in combination with the nutrient-rich ocean conditions created by the physical process of upwelling, produces a lush feeding ground. for countless invertebrates, fishes (over 180 species), marine mammals (over 25 species), and seabirds (over 60 species). The undersea oasis of the Cordell Bank and surrounding waters teems with life and provides food for hundreds of thousands of seabirds that travel from the Farallon Islands and the Point Reyes peninsula or have migrated thousands of miles from Alaska, Hawaii, Australia, New Zealand, and South America. Cordell Bank is also known as the albatross capital of the Northern Hemisphere because numerous species visit these waters. The US National Marine Sanctuaries are administered and managed by the National Oceanic and Atmospheric Administration (NOAA) who work with the public and other partners to balance human use and enjoyment with long-term conservation. There are four major orders of seabirds: 1) Sphenisciformes – penguins 2) *Procellariformes – albatross, fulmars, shearwaters, petrels 3) Pelecaniformes – pelicans, boobies, cormorants, frigate birds 4) *Charadriiformes - Gulls, Terns, & Alcids *Orders presented in this seminar In general, seabirds have life histories characterized by low productivity, delayed maturity, and relatively high adult survival.

Photo credits: Society for the Protection of Prespa, unless stated otherwise. Introduction Visual identification of the Dalmatian pelican seems like a straightforward task, yet in sites used by both species (the Dalmatian pelican and the great white pelican) identification can be tricky, especially when the observer is located some distance away from the birds. Hardly any useful material has been published on the sequence of moults and plumages of the Dalmatian pelican, and this gap often creates confusion and uncertainty about the accuracy of data in regards to ageing of Dalmatian pelicans, as well as frequently undermining confidence in census numbers.

Our flight in from the UK was delayed so no time for any real birding on this first day of our “Chilled Birding Tour”. Our local guide Tijan and our ground crew met us at the airport. We piled into Tijan’s well used minibus as Little Swifts and Yellow-billed Kites flew above us. A short drive took us to our lovely small boutique hotel complete with pool and lovely private gardens, we were going to enjoy staying here. Having settled in we all met up for a pre-dinner drink in the warmth of an African evening. The food was delicious, and we chatted excitedly about the birds that lay ahead on this nine- day trip to The Gambia, the first time in West Africa for all our guests. At first light we were exploring the gardens of the hotel and enjoying the warmth after leaving the chilly UK behind. Both Red-eyed and Laughing Doves were easy to see and a flash of colour announced the arrival of our first Beautiful Sunbird, this tiny gem certainly lived up to its name! A bird flew in landing in a fig tree and again our jaws dropped, a Yellow-crowned Gonolek what a beauty! Shocking red below, black above with a daffodil yellow crown, we were loving Gambian birds already.

  • Kenyan Birding & Animal Safari Organized by Detroit Audubon and Silent Fliers of Kenya July 8Th to July 23Rd, 2019
    Kenyan Birding & Animal Safari Organized by Detroit Audubon and Silent Fliers of Kenya July 8th to July 23rd, 2019 Kenya is a global biodiversity “hotspot”; however, it is not only famous for extraordinary viewing of charismatic megafauna (like elephants, lions, rhinos, hippos, cheetahs, leopards, giraffes, etc.), but it is also world-renowned as a bird watcher’s paradise. Located in the Rift Valley of East Africa, Kenya hosts 1054 species of birds--60% of the entire African birdlife--which are distributed in the most varied of habitats, ranging from tropical savannah and dry volcanic- shaped valleys to freshwater and brackish lakes to montane and rain forests. When added to the amazing bird life, the beauty of the volcanic and lava- sculpted landscapes in combination with the incredible concentration of iconic megafauna, the experience is truly breathtaking--that the Africa of movies (“Out of Africa”), books (“Born Free”) and documentaries (“For the Love of Elephants”) is right here in East Africa’s Great Rift Valley with its unparalleled diversity of iconic wildlife and equatorially-located ecosystems. Kenya is truly the destination of choice for the birdwatcher and naturalist. Karibu (“Welcome to”) Kenya! 1 Itinerary: Day 1: Arrival in Nairobi. Our guide will meet you at the airport and transfer you to your hotel. Overnight stay in Nairobi. Day 2: After an early breakfast, we will embark on a full day exploration of Nairobi National Park--Kenya’s first National Park. This “urban park,” located adjacent to one of Africa’s most populous cities, allows for the possibility of seeing the following species of birds; Olivaceous and Willow Warbler, African Water Rail, Wood Sandpiper, Great Egret, Red-backed and Lesser Grey Shrike, Rosy-breasted and Pangani Longclaw, Yellow-crowned Bishop, Jackson’s Widowbird, Saddle-billed Stork, Cardinal Quelea, Black-crowned Night- heron, Martial Eagle and several species of Cisticolas, in addition to many other unique species.

  • The Status and Distribution of Spot-Billed Pelican Pelecanus Philippensis in Southern India
    FORKTAIL 21 (2005): 9–14 The status and distribution of Spot-billed Pelican Pelecanus philippensis in southern India V. KANNAN and RANJIT MANAKADAN Surveys for Spot-billed Pelican Pelecanus philippensis were conducted in southern India from May 2000 to April 2004. Population estimates were based on counts of birds at nesting colonies and of large congregations at foraging sites, supplemented by published and unpublished recent records. A population of 2,850–3,700 birds is estimated for the states of Andhra Pradesh, Karnataka, Tamil Nadu and Kerala, which is higher than earlier estimates. INTRODUCTION used in the analysis. In some cases the survey data were supplemented with secondary information obtained Spot-billed Pelican Pelecanus philippensis is one of the from forest department records, local people and most threatened of the seven species of pelicans in the birdwatchers. All counts were carried out rapidly from world. The total population is estimated to number watchtowers, vehicles, or on foot, to reduce the 2,500–5,000 individuals in South Asia, 3,000–5,000 chances of double counting. Counts at foraging sites individuals in South-East Asia and <25 individuals in were generally carried out from 07h00 to 09h00, while Sumatra (BirdLife International 2001, Wetlands those at colonies were carried out between 11h00 and International 2002). Populations are declining owing 14h00 when most of the adults would have returned to factors such as human disturbance at the nesting from the foraging grounds.

Presence of the Peruvian Pelican Pelicanus thagus in seabird colonies of Chilean Patagonia. Marine Ornithology 44: 27–30. Over the past few years, an increase in Peruvian Pelican Pelecanus thagus presence has occurred in southern Chile, along the coast of the Los Lagos region, at the southern end of its range. We evaluate the presence of the pelicans in seabird colonies of this region and describe their behavior and interactions with other seabird species. Three colonies were surveyed: San Pedro Bay Islets (40°55′S), Kaikué-Lagartija Island (41°48′S) and Caicura Island (41°42′S). Counts were carried out from boats, and age structure was determined based on plumage color. Pelicans were found to be numerous and included a high proportion of juveniles. With the exception of one pelican egg (unhatched) found at Caicura Island in December 2013, there was no evidence of pelican nesting. Potential competitive interactions between the pelicans and other seabirds were evident.
