Hungary & Transylvania
Although we had many exciting birds, the ‘Bird of the trip’ was Wallcreeper in 2015. (János Oláh) HUNGARY & TRANSYLVANIA 14 – 23 MAY 2015 LEADER: JÁNOS OLÁH Central and Eastern Europe has a great variety of bird species including lots of special ones but at the same time also offers a fantastic variety of different habitats and scenery as well as the long and exciting history of the area. Birdquest has operated tours to Hungary since 1991, being one of the few pioneers to enter the eastern block. The tour itinerary has been changed a few times but nowadays the combination of Hungary and Transylvania seems to be a settled and well established one and offers an amazing list of European birds. This tour is a very good introduction to birders visiting Europe for the first time but also offers some difficult-to-see birds for those who birded the continent before. We had several tour highlights on this recent tour but certainly the displaying Great Bustards, a majestic pair of Eastern Imperial Eagle, the mighty Saker, the handsome Red-footed Falcon, a hunting Peregrine, the shy Capercaillie, the elusive Little Crake and Corncrake, the enigmatic Ural Owl, the declining White-backed Woodpecker, the skulking River and Barred Warblers, a rare Sombre Tit, which was a write-in, the fluty Red-breasted and Collared Flycatchers and the stunning Wallcreeper will be long remembered. We recorded a total of 214 species on this short tour, which is a respectable tally for Europe. Amongst these we had 18 species of raptors, 6 species of owls, 9 species of woodpeckers and 15 species of warblers seen! Our mammal highlight was undoubtedly the superb views of Carpathian Brown Bears of which we saw ten on a single afternoon! 1 BirdQuest Tour Report: Hungary & Transylvania 2015 www.birdquest-tours.com We also had a nice overview of the different habitats of a Carpathian transect from the Great Hungarian Plain through the deciduous woodlands of the Carpathian foothills to the higher conifer-covered mountains. -

Conservation of Italian Autochthonous Domestic Pigeon Breeds Antonio Pizzuti Piccoli
International Journal of Environment, Agriculture and Biotechnology, 5(2) Available: https://ijeab.com/ Conservation of Italian Autochthonous Domestic Pigeon Breeds Antonio Pizzuti Piccoli Natura per Tutti Onlus Organization, – Via Monteroni n°1265, 00055 Ladispoli (RM) Italy. Abstract— In this work it is proposed an analysis of the conservation status of Italian autochthonous domestic pigeon breeds. As like as other domestic species, the domestic pigeon is undergoing a rapid decline. In Italy the pigeon breeding is an ancient practice anterior to the Roman period. Actually we have 11 autochthonous breeds, here described in their mainly characteristics, and for everyone is proposed the population size and the perspective of conservation for the future. An important and fundamental impulse to the conservation of these breeds has been given by the Italian Pigeon Breeders Federation – FIAC and its numerous members, which have preserved the biodiversity heritage of the domestic pigeon in Italy. Of the Italian autochthonous breeds, only three are considered not at risk, while the other are in the range size for the breeds considered threatened. Two breeds, the Rondone frill and the Parma Occhialone pigeon are now present with numbers that classify them in the "critical" category. For the Rondone frill a numerical increase program is being developed, for the Parma Occhialone pigeon the FIAC has activated a recovery and diffusion program. To guarantee a future for biodiversity of this interesting domestic species in Italy, will be necessary to encourage the breeding of these Italian autochthonous domestic pigeons. Keywords— pigeon breeds, conservation status, domestic pigeon, Italy, population size. I. INTRODUCTION In this context fits the domestic pigeon, which, like other It has been estimated that since domestication, in the last domesticated species, is undergoing a rapid decline. -

Columba Livia
Columba livia -- Gmelin, 1789 ANIMALIA -- CHORDATA -- AVES -- COLUMBIFORMES -- COLUMBIDAE Common names: Rock Dove; Common Pigeon; Pigeon biset; Rock DoveI 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., Wheatley, H. & Wright, L. Assessment Rationale European regional assessment: Least Concern (LC) EU27 regional assessment: Least Concern (LC) In Europe this species has an extremely 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 is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern in Europe. Within the EU27 this species has an extremely 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 stable, 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 in the EU27.

Parvez1, 2*, M. T. D. Akter2 and M. J. U. Sarder2 1Department of Anatomy and Histology, Hajee Mohammad Danesh Science and Technology University, Dinajpur-5200, Bangladesh; 2Department of Veterinary and Animal Sciences, University of Rajshahi, Rajshahi- 6205, Bangladesh ABSTRACT The experiment was conducted to characterize different breeds of pigeon phenotypically and to study their body biometry, which are available in the northern Bangladesh. During this study 30 farms were selected which have >20 pair of pigeons in the three study area namely Rajshahi, Natore and Pabna districts of Bangladesh. There about 15 breeds have been selected for the observation of phenotypic characteristics such as color of bill, eye, eyelid, skin, shank, toe, egg, head feather, neck feather, body feather, down feather, wing feather, tail feather and shape of bill, body and egg. The biometrical data were collected from the measurement of length of bill, head, body, shank, middle toe, wingspan and mature body weight. In this study the highest mean bill length was found 2.83±0.05cm in Strasser and lowest mean head length 5.00±0.00cm in Kormona, Nun and Jacobin. The highest mean body length was found 41.60±0.38cm in Strasser and lowest mean body length 30.00±0.43cm in Owl. The highest mean wingspan was found 81.00±0.51cm in Jacobin and lowest mean wingspan 60.45±0.76cm in kormona.
