Several other photos by Nick appear later in this newsletter. 2 Ornithological Snippets photo Stuart Kelly It’s been fairly quiet this month. Single Fiordland Crested Penguins were reported from Nugget Point on 29th January, and at Katiki Point on 12th February. 43 Black-fronted Terns were roosting on the river in Balclutha on 15th February, while an Arctic Skua was seen from Taiaroa Head on 18th (the only other Otago sighting so far this season was at Katiki Point on 14th January). Sharon Roberts saw lots of Sooty Shearwaters offshore at Jacks Bay on 28th January, along with 2 Peafowl nearby, and 2 Grey-tailed Tattlers at Cabbage Point. A returning White Heron was at Tomahawk Lagoon on 12th & 19th February, and one was reported from Saint Leonards on 15th. The only passerine on offer this month is a leucistic House Sparrow at Mosgiel, seen and photographed by Robert Budd. 3 The following two pieces are related by Maree Johnstone. Members may have noticed a photo of a Paradise Duck family taken by Stephen Jaquiery at Burkes Inlet and published in the ODT in November 2018. -
Differentially Expressed Genes Match Bill Morphology and Plumage Despite Largely Undifferentiated Genomes in a Holarctic Songbird
Molecular Ecology (2015) doi: 10.1111/mec.13140 Differentially expressed genes match bill morphology and plumage despite largely undifferentiated genomes in a Holarctic songbird NICHOLAS A. MASON*† and SCOTT A. TAYLOR*† *Department of Ecology and Evolutionary Biology, Cornell University, 215 Tower Rd., Ithaca, NY 14853, USA, †Fuller Evolutionary Biology Program, Laboratory of Ornithology, Cornell University, 159 Sapsucker Woods Road, Ithaca, NY 14850, USA Abstract Understanding the patterns and processes that contribute to phenotypic diversity and speciation is a central goal of evolutionary biology. Recently, high-throughput sequencing has provided unprecedented phylogenetic resolution in many lineages that have experienced rapid diversification. The Holarctic redpoll finches (Genus: Acanthis) provide an intriguing example of a recent, phenotypically diverse lineage; traditional sequencing and genotyping methods have failed to detect any genetic differences between currently recognized species, despite marked variation in plumage and mor- phology within the genus. We examined variation among 20 712 anonymous single nucleotide polymorphisms (SNPs) distributed throughout the redpoll genome in com- bination with 215 825 SNPs within the redpoll transcriptome, gene expression data and ecological niche modelling to evaluate genetic and ecological differentiation among currently recognized species. Expanding upon previous findings, we present evidence of (i) largely undifferentiated genomes among currently recognized species; (ii) substantial niche -
Advances in the Study of Irruptive Migration
Advances in the study of irruptive migration Ian Newton1 Newton I. 2006. Advances in the study of irruptive migration. Ardea 94(3): 433–460. This paper discusses the movement patterns of two groups of birds which are generally regarded as irruptive migrants, namely (a) boreal finches and others that depend on fluctuating tree-fruit crops, and (b) owls and others that depend on cyclically fluctuating rodent popula- tions. Both groups specialise on food supplies which, in particular regions, fluctuate more than 100-fold from year to year. However, seed- crops in widely separated regions may fluctuate independently of one another, as may rodent populations, so that poor food supplies in one region may coincide with good supplies in another. If individuals are to have access to rich food supplies every year, they must often move hun- dreds or thousands of kilometres from one breeding area to another. In years of widespread food shortage (or high numbers relative to food supplies) extending over many thousands or millions of square kilome- tres, large numbers of individuals migrate to lower latitudes, as an ‘irruptive migration’. For these reasons, the distribution of the popula- tion, in both summer and winter, varies greatly from year to year. In irruptive migrants, in contrast to regular migrants, site fidelity is poor, and few individuals return to the same breeding areas in succes- sive years (apart from owls in the increase phase of the cycle). Moreover, ring recoveries and radio-tracking confirm that the same indi- viduals can breed in different years in areas separated by hundreds or thousands of kilometres. -

It is clear to us, that these businesses are more abundant than anyone suspects, and that they flourish considerably more than we care for. By monitoring these illegal practices, we hope to succeed in keeping them in check. There are places in the south, where so-called “bird fairs” are still safely taking place.” This text comes from the annual report of Vogelbescherming in 1936/1937. However, it could just as easily have been written today because there are still bird fairs taking place in scores of places all over the country. -
Arctic Redpoll Identification Revisited 1
ARCTIC REDPOLL IDENTIFICATION REVISITED 1 ARCTIC REDPOLL IDENTIFICATION REVISITED By Lee G R Evans SCANDINAVIAN ARCTIC REDPOLL ( Carduelis exilipes ) Scandinavian Arctic Redpoll, Maywick, Shetland, November 2010 (Hugh Harrop http://hughharropwildlifephotography.blogspot.com/ Lee G R Evans © British Birding Association/UK & Ireland 400 Club ARCTIC REDPOLL IDENTIFICATION REVISITED 2 SCANDINAVIAN ARCTIC REDPOLL Carduelis exilipes The Scandinavian Arctic Redpoll, or Coues’s Arctic Redpoll as it is sometimes known, breeds in Northern Europe eastwards into Siberia, extending from southern Novaya Zemlya, Finland, Sweden, Norway and in to northern Denmark. In southern Lapland, the species breeds in alpine Birch forests and overlaps with the breeding range of the Mealy Redpoll (Carduelis flammea ). Hugh Harrop has provided me with an excellent opportunity to revisit the identification of these Arctic Redpolls, as for the second autumn running, exceptional numbers of Hornemann’s Redpolls have reached Shetland and more latterly, Scandinavian Arctics have been appearing in numbers. This has allowed Hugh to obtain some signature images. The individuals I have used in my photo-essay are classic individuals, by which I use my yard-stick of identification limitations. I believe only classic or near-classic birds should be identified with confidence and published as such. FIELD CHARACTERS OF EXILIPES ARCTIC REDPOLL Using Hugh’s fabulous images as a guide, Scandinavian Arctic Redpoll can be separated from a well-marked Mealy Redpoll by the following criteria -: 1) Overall whiteness of plumage, with variable amounts of light streaking on the flanksides and predominantly gleaming white undertail coverts, often with a single evenly narrow dark shaft-streak on the longest feather; 2) A noticeably ‘pinched-in’ short, concave bill, in contrast to the typical long, pointed bill of Mealy. -

Worcestershire Redpolls and a Guide to Their Separation
Worcestershire Redpolls and a guide to their separation Plate 1 - Lesser Redpolls, Wyre Forest, Worcestershire, December 2005. © John Robinson In a landlocked county like Worcestershire, the arrival of winter finch flocks undoubtedly enthuses county birders during the winter months, particularly those who find gulls and waterfowl less than inspiring. With a little effort, ten species are obtainable annually, including Brambling, Common Crossbill, Hawfinch, Lesser Redpoll and Siskin; whilst Mealy Redpoll and Twite may boost this total, though the latter has become extremely scarce locally in recent years. The planting of game crops, primarily designed to provide food and cover for Pleasant and Partridge prior and during the winter shoots, inevitably attract large winter finch flocks, particularly Linnet, Goldfinch, Greenfinch, Chaffinch, Brambling and Redpoll. These sites provide observers the best opportunely to study these birds, being confined to a relatively small area, allowing close and often prolonged, eye-level views to be obtained. Though generally not the most colourful of our finches, Redpoll still possess a striking combination of black, buff and white plumage contrasts, whilst a male’s vivid crimson breast is no less than spectacular. Numbers may fluctuate from one winter to the next, but in years when the Silver Birch crop fails in Scandinavia, mass eruptions occur. During these periods Redpoll can become very numerous, particularly along the east coast of Britain, hence good-sized flocks often arrive in Worcestershire at this time. These flocks comprise both Lesser and Mealy Redpolls, with Arctic also a possibility and species separation can often challenge even the most experienced observers. Redpoll has been slip into three species, Lesser Redpoll (Acanthis cabaret), Common Redpoll (Acanthis flammea) and Arctic Redpoll (Acanthis hornemanni). -
Poland: Best of Eastern Europe
POLAND: BEST OF EASTERN EUROPE 25 APRIL – 10 MAY 2022 25 APRIL – 10 MAY 2023 We could find the striking Spotted Nutcracker at several locations on our Poland tour. www.birdingecotours.com [email protected] 2 | ITINERARY Poland: Best of Eastern Europe In this Poland: Best of Eastern Europe tour, we will visit the best birding locations that eastern and southern Poland have to offer, which we actually rate as some of the best birdwatching in the whole of Europe. During this exciting small group tour, we will explore vast river floodplains with bird- rich marshes, stunning primeval ancient woodlands, spectacular forested mountains and high peaks, and small-scale farmland, all dotted with quaint traditional villages that combine to give the feeling of stepping back in time several hundred years. We will spend time in and around these quiet, charming villages, where the wildlife will be right on our doorstep, adding to the fantastic experience we will have in Poland. We are sure you will love this tour as much as we do! Poland is one of the best countries for birding in Europe, ranking as one of our favorite destinations, and for good reason! Following International Ornithological Congress (IOC) taxonomy (v10.2 in December 2020) the bird list of Poland stands at a whopping 471 species, with a good number of these being highly sought-after by world birders. Poland is the best country in the world for seeing the rare Aquatic Warbler and Great Snipe, along with the possibility of seeing most of Europe’s woodpeckers. Throw in a decent mix of owls, some amazing raptors, plenty of shorebirds, gorgeous flycatchers, the chance of Wallcreeper, some very special warblers, as well as some excellent migrants, this destination should be very high on the list of ‘must see’ places. -

Recognize additional species in the Aulacorhynchus “prasinus” toucanet complex Background: The AOU (1998) presently considers there to be just one species of Aulacorhynchus prasinus, which ranges from Mexico to Guyana and Bolivia. This taxon’s range combines the taxonomic oversight regions of both the North American and South American classification committees, so this proposal is designed to be submitted to both, with committee-structured voting sections at the end. This is easy to do biologically, because the taxa fall out fairly neatly split between North and South America.
