Wetland Birds in the Recent Fossil Record of Britain and Northwest Europe John R
Wetland birds in the recent fossil record of Britain and northwest Europe John R. Stewart 18. Dalmatian Pelican Pelecanus crispus, Deep Bay, Mai Po, Hong Kong, February 1995. Geological evidence suggests that Dalmatian Pelicans bred in Britain, and in other western European countries (including The Netherlands and Denmark), prior to and during the Iron Age. Ray Tipper. ABSTRACT Wetland habitats in Britain and other parts of western Europe have been severely depleted during the latter part of the Holocene owing principally to drainage and land reclamation. Changes in the distribution of a number of wetland bird species can be gauged from archaeological and geological site records of larger birds, whose remains are generally better preserved. Key species are discussed here, including a heron Nycticorax fenensis and a crane Grus primigenia, two extinct species named on possibly uncertain fossil evidence. We can let our minds wander back to the misty realms of fifteen hundred years ago, to a wonderful Britain which was alive with bird song from coast to coast, which sheltered wolves, bears and boars in its dark woodlands, cranes in its marshes, bustards on its heaths and beavers by its streams, and we can visualize the great pink pelican sweeping on its huge pinions over the reedy waterways which then penetrated by secret paths into the very heart of what is now Somerset.

New Zealand Comprehensive III 16Th November – 2Nd December 2017 Trip Report
New Zealand Comprehensive III 16th November – 2nd December 2017 Trip Report Gibson’s Wandering Albatross off Kaikoura by Erik Forsyth Trip Report compiled by Tour Leader Erik Forsyth Rockjumper Birding Tours | New Zealand www.rockjumperbirding.com Trip Report – RBL New Zealand - Comprehensive III 2017 2 Daily Diary New Zealand is a must for the serious seabird enthusiast. Not only will you see a variety of albatrosses, petrels and shearwaters, but there are good chances of getting out on the high seas and finding something unusual. Seabirds dominate this tour, and views of most birds are right alongside the boat. There are also several land birds which are unique to these islands: the kiwis – terrestrial nocturnal inhabitants; the huge swamp-hen like takahe – prehistoric in its looks and movements; and then the wattlebirds (the saddlebacks and kokako) – poor flyers with short wings, which bound along the branches and on the ground. We had so many highlights on this tour, including close encounters with Little Spotted Kiwi, walk-away views of a pair of North Island Kokako, both North and South Island Saddlebacks and a pair of the impressive South Island Takahe. With many boat trips, the pelagic list was long, with Wandering, Northern and Southern Royal, Salvin’s, Black-browed, Campbell and White-capped Albatrosses, Westland, Cook’s and White- chinned Petrels, Buller’s, Flesh-footed and New Zealand (Red-breasted) Plover by Erik Forsyth Hutton’s Shearwaters, and Common Diving Petrel being a few of the highlights. Other major highlights included twelve New Zealand King Shag, a pair of Blue Duck with one chick, nine of the critically endangered Black Stilt, the rare Stitchbird, New Zealand Kaka, the entertaining Kea, range- restricted New Zealand Rockwren, the tiny Rifleman and lastly the striking Yellowhead, to name a few. -

Braz J Vet Parasitol 2020; 29(3): e003920. https://doi.org/10.1590/S1984-29612020049 Abstract The Neotropic cormorant Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) is widely distributed in Central and South America. In Chile, information about parasites for this species is limited to helminths and nematodes, and little is known about other parasite groups. This study documents the parasitic fauna present in 80 Neotropic cormorants’ carcasses collected from 2001 to 2008 in Antofagasta, Biobío, and Ñuble regions. Birds were externally inspected for ectoparasites and necropsies were performed to examine digestive and respiratory organs in search of endoparasites. -
Phylogenetic Patterns of Size and Shape of the Nasal Gland Depression in Phalacrocoracidae
PHYLOGENETIC PATTERNS OF SIZE AND SHAPE OF THE NASAL GLAND DEPRESSION IN PHALACROCORACIDAE DOUGLAS SIEGEL-CAUSEY Museumof NaturalHistory and Department of Systematicsand Ecology, University of Kansas, Lawrence, Kansas 66045-2454 USA ABSTRACT.--Nasalglands in Pelecaniformesare situatedwithin the orbit in closelyfitting depressions.Generally, the depressionsare bilobedand small,but in Phalacrocoracidaethey are more diversein shapeand size. Cormorants(Phalacrocoracinae) have small depressions typical of the order; shags(Leucocarboninae) have large, single-lobeddepressions that extend almost the entire length of the frontal. In all PhalacrocoracidaeI examined, shape of the nasalgland depressiondid not vary betweenfreshwater and marine populations.A general linear model detectedstrongly significant effectsof speciesidentity and gender on size of the gland depression.The effectof habitat on size was complexand was detectedonly as a higher-ordereffect.

Marlborough Sounds Wildlife Identification Guide
MARLBOROUGH SOUNDS WILDLIFE IDENTIFICATION GUIDE I NZKS operates several Salmon Farms in the Marlborough Sounds. NZKS works continuously to manage and minimise our impact on marine mammals and sea birds within the surrounding environment. An important part of our social license is to monitor wildlife activity around our farms, of which there is an abundance. Reported sightings of a specific species like King Shag can help identify patterns and trends and improve the science-based knowledge around these species and their behaviours. Information captured will also support consent requirements and future consent applications. Mammals and seabirds are instinctively attracted to the farms for shelter and food. Our focus is on minimising the risks in our daily activities and on working in harmony. This document will outline species that could visit our farms. Please use this document to help you identify any wildlife you are unsure of. Please do your utmost NOT to interact with any wild mammal or seabird, but in an event where you need to interact with them please refer to our NZKS Marine Mammal and Shark Management Plan to identify the best course of action. In the event of a wild animal dying in and around our farm, notify your manager as soon as possible. He or she will report it to the Department of Conservation (DoC) and guide you on the next course of action. Please report details of sightings or entanglements of these species to your manager: • ANY stranded/in danger wildlife • Tagged Fur seal • Leopard seal • Southern right whales SEALS • Great white II • Basking sharks • New Zealand King Shag CONTENTS Seals ............................. -
