Jynx Torquilla Jynx torquilla -- Linnaeus, 1758 ANIMALIA -- CHORDATA -- AVES -- PICIFORMES -- PICIDAE Common names: Eurasian Wryneck; European Wryneck; Torcol; Wryneck 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 appears to be increasing, 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 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 increasing, 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.

The population in the EU27 is estimated at 287,000-727,000 pairs, which equates to 574,000-1,450,000 mature individuals. For details of national estimates, see Supplementary PDF. Trend In Europe and the EU27 the population size is estimated to be increasing. For details of national estimates, see Supplementary PDF. Habitats and Ecology This species is widespread over most of lowland Europe, and also occurs in low numbers in mountainous areas. Breeding occurs in a variety of forest-types, from dry pine (Pinus) stands to riparian forest. Dense forest blocks are avoided, the birds tending to settle along south-facing forest edges, or in clear-felled or burned patches. Where summers are relatively cold or humid, localities with dry sandy soil are preferred (Tucker and Heath 1994). It is territorial and partners display by head-swinging with ruffled head feathers. Laying occurs from May to June. The nest-site is selected by both sexes and is usually in a natural cavity, an old hole of another woodpecker, or an artificial nestbox. Typically seven to twelve eggs are laid (Winkler and Christie 2002). It feeds mostly on the larvae and pupae of ants. In northern areas or during bad weather insects, spiders, even tadpoles and berries may be fed to young (Tucker and Heath 1994). Across most of its range, it is fully migratory and winters mainly in south of the Sahara and occasionally in the Mediterranean basin (Hagemeijer and Blair 1997).

Since the 1950s, the loss of important habitats such as orchards and unimproved meadows and the replacement of hardwoods with conifers have also caused declines and the conversion of many areas to agriculture combined with an increase in the use of pesticides have also decreased the abundance of ants (Tucker and Heath 1994).

It is listed as a priority species in the U.K. Biodiversity Action Plan. Conservation Actions Proposed The use of pesticides should be reduced in agricultural areas and orchards and low-intensity management techniques applied to meadows, pastures and orchards in order to help sustain ant populations. These habitats should also be preserved from conversion to intensively managed open fields or commercial forestry plantations. In addition suitable nest-sites in woods and along forest edges should be protected and where nest- sites are limiting, nest boxes should be erected (Tucker and Heath 1994).

  • Explicit Nation-Wide Habitat Models for Common Italian Piciformes
    Avocetta 33: 115-122 (2009) Explicit nation-wide habitat models for common Italian Piciformes Tommaso Campedelli2, GuGlielmo londi2, lorenzo mini2, Guido Tellini Florenzano1,2 1 MITO2000, National Committee 2 DREAM Italia - Via Garibaldi 3, I-52015 Pratovecchio (AR), Italy ([email protected]) Abstract – The aim of this paper is to assess the effect of broad scale environmental and geographical variables on the presence of Italian commonest breeding Piciformes (Wryneck, Green, Black, and Great Spotted Woodpeckers). Using the data of MITO2000 (2000-2003), logistic regression models were built, relating their presence with area occupied by Corine land-use categories, habitat diversity, morpho- logical and elevation-range, latitude and longitude. Our analyses seem to give some basic information about large scale ecology of the species, allowing to indicate different habitat types (heterogeneus habitat for Wryneck, broadleaved woods for Green Woodpecker, woods for Great Spotted Woodpecker). Our models clearly show the importance of geographical variables to infer how species ecology chang- es at different latitudes: Green and Great Spotted Woodpecker for example, become commoner, and less linked to woods, northwards. INTRODUCTION 2003, Brotons et al. 2004a, Rushton et al. 2004). Although some doubts on their effectiveness still remain (Gutzwiller Woodpeckers are typically considered forest species and and Barrow 2003, Chamberlain et al. 2004), these tech- efficient woodland biodiversity indicators, from local niques, if correctly applied, have proved to be valuable (Mikusinski et al. 2001) to continental scale (Mikusinski tools for the knowledge of the actual distribution of spe- and Angelstam 1998). Moreover, the ecology of wood- cies and to obtain objective information on the main eco- peckers is complex: they show a different degree of spe- logical factors affecting their presence (Guisan and Zim- cialization (Angelstam and Mikusinski 1994) and, even merman 2000, Scott et al.

  • Newsletter Number 27– October 2014
    P O Box 93, Wakkerstroom 2480 Cell Number 0822556778 E-Mail: [email protected] NEWSLETTER NUMBER 27– OCTOBER 2014 CONTROLLED BURN IN THE WETLAND – John Burchmore On Tuesday 14th October, a controlled burn was successfully carried out near the bridge on the right hand side of the Amersfoort road, next to the poplars. In this specific area there is some Salt Marsh Rush, Juncus kraussii (incema Zulu). The thin strong stem of this reed is one of the favourite weaving materials in KwaZulu–Natal, especially for making the traditional sleeping mats or incansi and is an important source of income for rural people. These mats made from incema stems are of high quality and they last much longer than similar mats made from other sedges. The reeds were dying back due to the increase of moribund material around the rhizomes, possibly because of very few fires in this area of the wetland during the last ten years. Towards the end of summer some of the residents in eSizameleni harvest the reeds, and they requested that the area be burnt to stimulate the growth of the plants. The burn was carried out by the Working on Fire team which is based at BirdLife South Africa Wakkerstroom Centre, after permission had been obtained from the Fire Chief in Volksrust.

Freitag et al. This paper describes an original autonomous system based on the Passive Integrated Transponder (PIT) technology for monitoring the feeding activity of small birds at their nest. It is installed on pre-existing nest boxes which were slightly modified for the monitoring purposes. The system operates autonomously for at least 7 days and recorded data can be collected using a simple pocket calculator or a standard laptop. The monitoring capabilities of the system include the arrival times of each adult, tagged with a PIT attached to one leg, and the regular collecting of microclimatic data. In the present study, the internal and external temperatures of the nest were recorded. The autonomous system was validated during two weeks as part of a more extended study on Wryneck (Jynx torquilla L.) foraging strategies. Its efficacy was confirmed by comparison with conventional photographs of birds at each feeding and climatic station data.

  • Vertebrata: Aves: Piciformes) and Implications for Creationist Design Arguments P.A
    OPEN ACCESS JCTS Article SERIES B Baraminological Analysis of the Picidae (Vertebrata: Aves: Piciformes) and Implications for Creationist Design Arguments P.A. Garner Biblical Creation Ministries, Soham, Cambs, UK Abstract The Picidae (woodpeckers, wrynecks and piculets) comprise a family within the near passerine order Piciformes. Creationists have often appealed to the unique anatomical and behavioural specializations found in woodpeckers as evidence of divine design. However, until now no baraminological studies of the group have been undertaken. This paper reports a baraminic distance correlation analysis of 50 morphological characters (mostly related to hind limb musculature) and 20 taxa (12 picids and eight outgroup taxa). The results show that the woodpeckers, wrynecks and piculets form a well-defined group united by significant positive correlation and separated from seven of the eight outgroup taxa (barbets, toucans and toucanets) by significant negative correlation. The eighth outgroup taxon, the honeyguide Indicator, was neither positively nor negatively correlated with the other taxa in the dataset. Multidimensional scaling applied to the baraminic distances revealed an orthogonal pattern with ingroup taxa arranged on one axis and outgroup taxa on another, a result that has previously been interpreted as mitigating conclusions of negative discontinuity. However, repeating the analysis without the genus Indicator, which formed one of the axes, did not change the negative correlation between the picids and non-picids, suggesting that the result cannot be dismissed merely as an artefact of the multidimensional scaling pattern. The results suggest that all members of the Picidae constitute a single holobaramin. This conclusion is consistent with hybridization data indicating the monobaraminic status of at least 12 genera in six of the nine tribes within the Picidae.

Nat. Croat., Vol. 29, No. 1., 123-128, 2020, Zagreb. In this article I shall present data on the characteristics of the eggs of the Eurasian wryneck, Jynx torquilla, collected in north-western Croatia during the period from 1985 to 2018 using wood nest- boxes. Nestboxes were primarily installed for investigation of Passerine bird species (tits Parus sp., tree sparrow Passer montanus and nuthatch Sitta europaea), but approximately one out of a hundred nest- boxes per year was occupied by the Eurasian wryneck. In this study, 34 clutches in total were sampled during the first nesting in the study period, after all eggs had been laid. In this paper, oological data of the Eurasian wryneck in the south-eastern Europe area are presented for the first time. It is worth not- ing, however, that such data are scarce for the whole of Europe. Average number of eggs per clutch was 8.1 (from 6 to 10). Egg length ranged from 17.7 to 21.9 mm (mean = 20.1 mm), egg breadth from 14.2 to 15.9 mm (mean = 15.1 mm), egg volume from 1856.4 to 2668.9 mm³ (mean = 2347.5 mm³) and elongation index from 1.19 to 1.43 (mean = 1.33).
