Raptors typically hunt and [Class of Birds] kill their prey. Small lizards and frogs are preyed upon by a great Accipitriformes variety of animals (Duellman & Trueb 1986; Greene 1988; Zug [Order of diurnal birds of prey] 1993). Here we have recorded a predation upon Desert Monitor Accipitridae Varanus griseus and Dusky Crag Martin Ptyonoprogne concolor [Family of Hawks and by Bonelli’s Eagle Aquila fasciata in Thar Desert of Rajasthan.

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. -

Visual Adaptations of Diurnal and Nocturnal Raptors
Seminars in Cell and Developmental Biology 106 (2020) 116–126 Contents lists available at ScienceDirect Seminars in Cell & Developmental Biology journal homepage: www.elsevier.com/locate/semcdb Review Visual adaptations of diurnal and nocturnal raptors T Simon Potiera, Mindaugas Mitkusb, Almut Kelbera,* a Lund Vision Group, Department of Biology, Lund University, Sölvegatan 34, S-22362 Lund, Sweden b Institute of Biosciences, Life Sciences Center, Vilnius University, Saulėtekio Av 7, LT-10257 Vilnius, Lithuania HIGHLIGHTS • Raptors have large eyes allowing for high absolute sensitivity in nocturnal and high acuity in diurnal species. • Diurnal hunters have a deep central and a shallow temporal fovea, scavengers only a central and owls only a temporal fovea. • The spatial resolution of some large raptor species is the highest known among animals, but differs highly among species. • Visual fields of raptors reflect foraging strategies and depend on the divergence of optical axes and on headstructures • More comparative studies on raptor retinae (preferably with non-invasive methods) and on visual pathways are desirable. ARTICLE INFO ABSTRACT Keywords: Raptors have always fascinated mankind, owls for their highly sensitive vision, and eagles for their high visual Pecten acuity. We summarize what is presently known about the eyes as well as the visual abilities of these birds, and Fovea point out knowledge gaps. We discuss visual fields, eye movements, accommodation, ocular media transmit- Resolution tance, spectral sensitivity, retinal anatomy and what is known about visual pathways. The specific adaptations of Sensitivity owls to dim-light vision include large corneal diameters compared to axial (and focal) length, a rod-dominated Visual field retina and low spatial and temporal resolution of vision. -

Rabbit Burrows Or Artificial Refuges Are a Critical Habitat Component for the Threatened Lizard, Timon Lepidus
Biodivers Conserv (2010) 19:2039–2051 DOI 10.1007/s10531-010-9824-y ORIGINAL PAPER Rabbit burrows or artificial refuges are a critical habitat component for the threatened lizard, Timon lepidus (Sauria, Lacertidae) Pierre Grillet • Marc Cheylan • Jean-Marc Thirion • Florian Dore´ • Xavier Bonnet • Claude Dauge • Sophie Chollet • Marc Antoine Marchand Received: 20 August 2009 / Accepted: 25 February 2010 / Published online: 19 March 2010 Ó Springer Science+Business Media B.V. 2010 Abstract Refuges are crucial for most animal species as they offer essential protection against predators and provide buffered environmental conditions to their occupants. Our data show that northern populations of the threatened ocellated lizard (Timon lepidus) depend on the availability of the burrows excavated by the European rabbit (Oryctolagus cuniculus). In the last decade, a severe decline in rabbit populations has had a disastrous effect on lizard numbers. To compensate for the lack of refuges, artificial shelters were constructed in autumn 2005 and 2007 and were monitored the following years (2006– 2009). Most of the artificial refuges were rapidly occupied by lizards, notably juveniles, suggesting that this technique was successful to improve lizard habitat. Because other factors such as food resources might be also crucial, further assessments are required to determine if artificial refuges are sufficient to stem population decline. These results nonetheless provide an encouraging option to maintain and/or to restore threatened pop- ulations, for instance through a buffering of rabbit burrow fluctuations. More generally, the P.

From east to west crosses the Douro River, whose basin occupies 82% of the territory. The river network dense in mountainous areas, weaker in the central plains, delimits towns and cities and is the lifeblood of the old and new agricultural landscapes, and largely also the landscapes of the industrial era.
