Turdus Pilaris Turdus pilaris -- Linnaeus, 1758 ANIMALIA -- CHORDATA -- AVES -- PASSERIFORMES -- TURDIDAE Common names: Fieldfare; 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: Vulnerable (VU) 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 <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to 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 Europe. In the EU27 the species is undergoing rapid declines, and it is therefore classified as Vulnerable. Since the wider European population is also decreasing, there is not considered to be significant potential for rescue from outside the EU27 and the final category is unchanged. Occurrence Countries/Territories of Occurrence Native: Albania; Austria; Azerbaijan; Belarus; Belgium; Bosnia and Herzegovina; Bulgaria; Croatia; Cyprus; Czech Republic; Denmark; Greenland (to DK); Estonia; Finland; France; Germany; Greece; Hungary; Iceland; Ireland, Rep. of; Italy; Latvia; Liechtenstein; Lithuania; Luxembourg; Macedonia, the former Yugoslav Republic of; Malta; Montenegro; Netherlands; Norway; Poland; Portugal; Romania; Russian Federation; Serbia; Slovakia; Slovenia; Spain; Sweden; Switzerland; Turkey; Ukraine; United Kingdom Vagrant: Faroe Islands (to DK); Svalbard and Jan Mayen (to NO); Gibraltar (to UK) Population The European population is estimated at 14,200,000-28,600,000 pairs, which equates to 28,400,000-57,300,000 mature individuals. The population in the EU27 is estimated at 3,060,000-4,700,000 pairs, which equates to 6,110,000-9,390,000 mature individuals. For details of national estimates, see Supplementary PDF. Trend In Europe the population size is estimated to be decreasing by less than 25% in 15.6 years (three generations). In the EU27 the population size is estimated to be decreasing by 30-49% over the same period. For details of national estimates, see Supplementary PDF. Habitats and Ecology This species typically inhabits mixed habitat, mainly part-wooded and part-open country, commonly using trees for breeding and roosting and hedges and open ground for foraging. It breeds in boreal forests of mixed pine (Pinus) and birch (Betula), as well as scrub, clearings, parks and gardens. In high latitudes, relatively small numbers extend beyond the tree-line into alpine heathland and tundra scrub, and even to entirely bleak grassy islands in the extreme north. It winters mainly in lowlands, often in more open habitats, including grassy and cultivated fields, moorland edges, woodland edges and orchards. Breeding occurs from early April to late August, with timing varying with latitude. The nest is a bulky, untidy cup, made of twigs, roots, moss, lichen, grass and leaves, lined with animal hair, rootlets and fine grass, and cemented with mud. It is generally sited in the fork of a tree or against the trunk or on a branch, usually towards upper levels of tree and normally at least two metres off the ground but occasionally on ground, or in a cliff face. Normally lays five or six eggs. The diet is mainly invertebrates and fruits, but also takes berries and seeds in the winter, and shoots and buds in the spring. The species is migratory but movements are essentially irruptive and nomadic (Collar 2005).

  • What Is So Rare?
    WHAT IS SO RARE? As a Fieldfare in April? In Massachusetts, perhaps only a Western Reef Heron or a White-faced Ibis. April here is a month of avian surprises. The 1986 birdwatching spring was off to a happy start with the discovery by schoolteacher Ralph Richards, during a lonely vigil on the cold and rainy Sunday of April 6, of a Fieldfare Turdus pilaris) in a Concord cornfield near the Sudbury River. According ta a bulletin promptly issued by the Massachusetts Audubon Society, this is a first state record, and there have been, s-ince 1878, ten prior records in North America, the most recent being the occurrence of four Fieldfares in St. John's, Newfoundland, from December 1985 to mid-January 1986. "It seems not unlikely that the Massachusetts bird originated with the same midwinter flight that brought the Newfoundland birds to North America. ..." In winter, the Fieldfare ranges from southern Scandinavia, the British Isles, and central Europe south to the Mediterranean. Outside of the breeding season, the bird's habitat choice is open fields and pastures, where it occurs gregariously in large flocks, often accompanied by Redwings (Turdus iliacus). The Fieldfare nests in northern Scandinavia (it is Norway's most common thrush), in north and central continental Europe east to Siberia, and also in Iceland and southern Greenland. The story of the establishment of the disjunct Greenland population is well documented. In January 1937, a strong southeast gale swept a flock of Fieldfares across Europe and the Atlantic to the island of Jan Mayen and the Greenland coast.

  • EU Business and Biodiversity Platform
    EU Business and Biodiversity Platform Workstream 2: Innovation for Biodiversity and Business Innovation for reed bed biomass fuel and biodiversity by FIELDFARE – ANALYSIS OF THE OPPORTUNITY October 2015 Author: Guy Duke Contributing author: Paul Goriup (FIELDFARE) 1 BASIC INFORMATION 1.1 Companies and contact points FIELDFARE Contact: Paul Goriup, Managing Director, FIELDFARE Email: [email protected] Web: www.fieldfare.biz 1.2 Summary of the opportunity An innovation offering significant benefit to small rural businesses in a particular region of the EU (lower Danube) and offering significant enhancement of reed bed biodiversity in this region as well as larger populations along flyways of migrants benefiting from these reed bed enhancements. It offers a financially sustainable solution to reducing the extent of overgrown reed beds and eventually reverse ecologically unsustainable floodplain management in the lower Danube region. Good scalability in the lower Danube region with possible transfer to other reed bed areas in Europe, limited by reed bed area. There is a potential €40+ million per annum market from the lower Danube resource, generating 2000-2500 jobs. Feasibility currently constrained by inflexible standards, slow rate of innovation in management and processing technologies, and low diffusion of appropriate boiler equipment. 1.3 Description of the innovation FIELDFARE harnesses ethical investment in Western Europe to promote ecologically sustainable development and wise use of natural resources in Eastern Europe. It is particularly active in the Danube Delta, a region of high biodiversity, where relatively modest investment can generate large biodiversity benefits. The main innovation is the production of biomass fuel from overgrown, low biodiversity reed beds that have become widespread as a result of floodplain modification since the 1950s.

  • Rejection Behavior by Common Cuckoo Hosts Towards Artificial Brood Parasite Eggs
    REJECTION BEHAVIOR BY COMMON CUCKOO HOSTS TOWARDS ARTIFICIAL BROOD PARASITE EGGS ARNE MOKSNES, EIVIN ROSKAFT, AND ANDERS T. BRAA Departmentof Zoology,University of Trondheim,N-7055 Dragvoll,Norway ABSTRACT.--Westudied the rejectionbehavior shown by differentNorwegian cuckoo hosts towardsartificial CommonCuckoo (Cuculus canorus) eggs. The hostswith the largestbills were graspejectors, those with medium-sizedbills were mostlypuncture ejectors, while those with the smallestbills generally desertedtheir nestswhen parasitizedexperimentally with an artificial egg. There were a few exceptionsto this general rule. Becausethe Common Cuckooand Brown-headedCowbird (Molothrus ater) lay eggsthat aresimilar in shape,volume, and eggshellthickness, and they parasitizenests of similarly sizedhost species,we support the punctureresistance hypothesis proposed to explain the adaptivevalue (or evolution)of strengthin cowbirdeggs. The primary assumptionand predictionof this hypothesisare that somehosts have bills too small to graspparasitic eggs and thereforemust puncture-eject them,and that smallerhosts do notadopt ejection behavior because of the heavycost involved in puncture-ejectingthe thick-shelledparasitic egg. We comparedour resultswith thosefor North AmericanBrown-headed Cowbird hosts and we found a significantlyhigher propor- tion of rejectersamong CommonCuckoo hosts with graspindices (i.e. bill length x bill breadth)of <200 mm2. Cuckoo hosts ejected parasitic eggs rather than acceptthem as cowbird hostsdid. Amongthe CommonCuckoo hosts, the costof acceptinga parasiticegg probably alwaysexceeds that of rejectionbecause cuckoo nestlings typically eject all hosteggs or nestlingsshortly after they hatch.Received 25 February1990, accepted 23 October1990.

  • Population Trends of Common Birds in the Italian Alps
    Population Index of Common Breeding Birds in Italian Mountain Prairies Rural development: A critical opportunity for people and biodiversity With a spotlight on the Alpine region Turin 6 november 2013 Mountains cover almost a quarter of the Earth surface, host more than 16% of global human population but provide services to many more communities and people Mountains provide many kind of resources that have positive impacts on human health and its prosperity far beyond their natural boundaries. One for all, water The mountains contribute for the 16% to the Italian national GDP However, despite their importance, the conservation status of mountains is not so satisfactory and many problems exist. Some of these are related with human presence and activities, e.g. effects of climate change, pollution, settlement and infrastructures development and tourism pressure; others with the opposite phenomena e.g. changes in cultural landscape and decrease of open habitats, and their biodiversity, due to the land abandonment For these reasons, MITO2000 project (the Italian national common bird monitoring scheme) decided to focus on species breeding in mountain open habitats MITO2000 is part of PECBMS (Pan-European Common Bird Monitoring Scheme), a Europe-wide network of national breeding bird monitoring projects. This network produces indices of population trends of many breeding bird species. One of the most important index is the FBI (Farmland Bird Index), that is one of the EU indicators to assess the impact of agri- environment measures of the CAP These indices are “aggregated indices” because they are calculated averaging the population trends of some species, choosen on the basis of their shared ecological preferences Through objective procedures we identified a group of species breeding in mountain open habitats and, from 2009, we used them to build up a new aggregate index, named FBIpm ( Mountain Prairies Index) Some results .....

Trees in cities develop under more stressful conditions and are, therefore, more susceptible to parasite including mistletoe infestation. The aim of this study was to investigate the ecological, microclimatic, and landscape factors causing the spread of European mistletoe (Viscum album L.) in urban conditions. The most numerous hosts of mistletoe were Tilia cordata (24.4%), Acer platanoides (22.7%), and Populus nigra (16.7%). On average, there were more than 10 mistletoe bushes per tree. The mass mistletoe infestations (more than 50 bushes per the tree) were detected for Populus berolinensis, Populus nigra, × and Acer saccharinum. The largest number of infected trees was detected in the green zone (city parks), historical housing estates, and green zone along water bodies. Based on the results of principal component analysis (PCA), the main factors causing the spread of mistletoe on the urban territories are trees’ age and relative air humidity.

We used the extra time for shopping for supplies before returning to the airport to greet another arriving couple. All together we headed straight to our hotel at the edge of the small town of Bugyi. We checked into our rooms, sorted out the safe and other details, and proceeded to have lunch in the hotel restaurant. With some of the group present, we decided to use the rest of the afternoon to explore some of the nearby birding areas, which proved very productive. The area of Apaj Puszta with its marshes, fish farming ponds, and reedbeds held plenty of birds. Highlights included a Black Woodpecker perched on the top of a bare branch giving excellent views. We saw Purple Heron and a rather close Ferruginous Duck in a little channel. Huge flocks of Graylag Geese fed in the marshes along with Eurasian Spoonbills; Great and Little egrets were present as well and often were disturbed by the presence of several White-tailed Eagles in the area whose European Turtle-Dove © Balazs Szigeti appearance often put hundreds of birds into flight. A late migrant European Turtle-Dove was also posing well.
