The occurrence of woodpeckers in European forests depends on many forest stand characteristics. During the study conducted in 2013 in the agricultural landscape of SE Poland (in an extremely deforested area with a 5% share of forest area), the habitat requirements of Middle Spotted Woodpecker Dendrocoptes medius, Great Spotted Woodpecker Dendrocopos major and Syrian Woodpecker Dendrocopos syriacus were described. For this purpose, the degree of occupation by individual species of 73 forest patches was assessed over an area of 355 km2. To determine the habitat requirements of the woodpecker species, a set of 7 parameters characterizing the studied forests and their surroundings were determined, viz. forest patch area, average age of the tree stand, etc.). Generally, the Syrian Woodpecker inhabited small forest patches surrounded by a significantly larger proportion (2.3–5.6%) of orchards, compared to forests uninhabited by this species. The most important factors that positively influenced the occurrence of the Middle and Great Spotted Woodpeckers were the forest patch size, average age of the forest patch stand, and area of forest stands aged older than 80 years. The Great Spotted Woodpecker preferred forest patches with an area exceeding 15 ha, but the Middle Spotted Woodpecker occurred only in forest patches over 42 ha. Such minimum forest patch areas should be considered essential for protecting the two mentioned species in a heavily deforested landscape. Small-sized forest patches should also be protected, enabling refuge for the Syrian Woodpecker.

The several thousand hectares of nearly contiguous forests of the Bakony Hills, located in the middle of Transdanubia, are suitable habitats for all nine species of woodpeckers found in Hungary. In addition to literature work, field surveys were carried out to investigate the distribution of the species and the habitat types of the occurrences. During the research, it has been proven that the Great Spotted Woodpecker (Dendrocopos major) is the most common woodpecker species in Bakony Hills, followed by the Black Woodpecker (Dryocopus martius), the Grey-faced Woodpecker (Picus canus) and the Middle Spotted Woodpecker (Leiopicus medius). The density of White-backed Woodpeckers (Dendrocopos leucotos) in the study area was surprisingly high.

Abstract The main goal of this study is to get a better insight of the habitat requirements for the Great- and Middle Spotted Woodpeckers. Woodpeckers are forest specialists, threatened all over Europe mainly by the loss of forest habitats and also by the loss in quality of the habitat by reducing the food sources and nesting sites. Both species showed a strong preference for oaks, lime, large trees and dead wood for nesting, but Middle Spotted Woodpecker proved to be more selective in terms of tree species. Nest-height was influenced by tree diameter. Both species have the same nesting preferences for Turkey oak, lime and Pedunculate oak, in a Quercetum farnetto-cerris type of forest. The orientation of the nest hole on the tree was mainly NE-E-SE for Middle Spotted Woodpecker and N-NE-E for Great Spotted Woodpecker.

From 1997–2003, forest management measures in favour of the vulnerable middle spotted woodpecker were conducted in an oak-hornbeam forest in northern Switzerland. In this study,we examine the consequences of these measures on population size and location of breeding cavities of middle spotted and great spotted woodpeckers. We found that population sizes of both species remained stable despite considerable forestry action taken in old oaks stands of vital importance for these woodpeckers. In areas where the two management measures «coppice-with-standards» and «thinning of coppicewith-standards stands» were applied, no differences in the number of breeding cavities of both species immediately before and after management intervention measures could be found. However, the proportion of breeding cavities of the great spotted woodpecker increased in old oak stands which were not subjected to management measures, while middle spotted woodpeckers used such stands as expected from their availability. We conclude that the two forest management measures are, at least on the short run, appropriate to the ecological requirements of the two woodpecker species.

The role of oak, deadwood and ivy for habitat selection of the middle spotted woodpecker Due to their habitat needs, woodpeckers are generally considered to be excellent indicators of forest habitat quality and biodiversity. In the EU and in Switzerland, the middle spotted woodpecker acts as a flagship species for nature conservation in forests. After several decades of decline in the Canton of Zurich, the population of the indicator species more than doubled between 2002 and 2012. The reasons for this positive development are so far unknown. It is hypothesized that an increased availability of ivy berries, sometimes eaten by the middle spotted woodpecker, may have contributed to the population growth. Based on the woodpecker monitoring 2012 in the Canton of Zurich, in 2013 the availability of trees with ivy berries at sites with and without presence of the middle spotted woodpecker was examined in eight forests. At the same time we also studied the availability of oaks and standing dead trees, two habitat factors well known to be important for the middle spotted woodpecker. Results revealed significantly shorter distances to large oaks and a tendency towards shorter distances to dead trees at points with middle spotted woodpecker presence than at points without. The distance to trees with ivy berries, on the other hand, was the same at presence and absence points. Occurrence probability of the middle spotted woodpecker was best explained by the distances to the closest large oak and to the closest standing dead tree, respectively. The importance of ivy contributing to the structural diversity in forest ecosystems and providing food and refuge to many species is widely recognized. Therefore, ivy should not be eliminated and oaks and dead trees should be continued to be fostered.

Woodpecker diversity is usually higher in natural forests rich in dead wood and old trees than in managed ones, thus this group of birds is regarded as an indicator of forest biodiversity. Woodpeckers excavate cavities which can be subsequently used by several bird species. As a consequence, their abundance indicates high avian abundance and diversity in forests. However, woodpecker-made holes may be also important for other animals, for example, mammals but it has seldom been investigated so far. Here, we examine how well one species, the Great Spotted Woodpecker, predicts species richness, occurrence and acoustic activity of bats in Polish pine forests. In 2011 we conducted woodpecker and bat surveys at 63 point-count sites in forests that varied in terms of stand age, structure and amount of dead wood. From zero to five Great Spotted Woodpeckers at a point-count site were recorded. The total duration of the echolocation calls during a 10-min visit varied from 0 to 542 s and the number of bat species/species groups recorded during a visit ranged between zero to five. The local abundance of the woodpecker was positively correlated with bat species richness (on the verge of significance), bat occurrence and pooled bat activity. The occurrence of Eptesicus and Vespertilio bats and Nyctalus species was positively related with the abundance of the Great Spotted Woodpecker. The activity of Pipistrellus pygmaeus, Eptesicus and Vespertilio bats and a group of Myotis species was not associated with the woodpecker abundance, but echolocation calls of Nyctalus species, P. nathusii and P.pipistrellus were more often at sites with many Great Spotted Woodpeckers. Moreover, the probability of bat presence and the activity of bats was generally higher shortly after dusk and in middle of the summer than in late spring. We suggest that the observed correlations can be driven by similar roosting habitats (e.g., woodpeckers can provide breeding cavities for bats) or possibly by associated invertebrate food resources of woodpeckers and bats. The abundance of Great Spotted Woodpecker seems to be a good positive indicator of bat species richness, occurrence and activity, thus adding a group of relatively cryptic forest species that are indicated by the presence of the Great Spotted Woodpecker.

AbstractThe Middle Spotted Woodpecker Dendrocopos medius is a highly specialised woodpecker inhabiting mature deciduous forests. The presence of large mature oaks Quercus sp. is a very important factor determining the species' presence and distribution. In Slovenia it is more common in the eastern part, where it inhabits mainly lowland flood-plain oak forests. In other parts of the country it is more localised, as is the case in western Slovenia, where small isolated populations were recently discovered. In this paper we present the currently known observations of Middle Spotted Woodpecker in the Karst region (W Slovenia), the results of the first systematic survey and the first documented breeding of the species in this area. The survey was carried out on the 20 of March 2016 in the wooded hills between the villages of Senožeče and Veliko polje. Using playback method we recorded a total of 8 territorial woodpeckers, confirming our initial expectations about the species' abundance in that area. Breeding was also confirmed in the hills of Senožeče, an active nest-hole was found on 23 Apr 2017. On 18 May 2017 at least 3 juveniles successfully left the nest. Middle Spotted Woodpeckers have recently been observed also in other oak woodlands across the Karst and nearby areas, especially outside the breeding season. These areas include Lipica, Bazovica, the Brkini hills and the Gorica Karst. From summer 2016 onwards several observations of Middle Spotted Woodpeckers have been reported from Lipica, involving up to four different individuals. Repeated sightings in this area and the presence of suitable habitat suggest a probable breeding. The increased number of data in western Slovenia during the last decade might be a consequence of more frequent field visits by ornithologists. Moreover, the presence of the Middle Spotted Woodpecker in this part of the country might be linked to the gradual spreading of forests and the maturing of oak stands already present here. In the above-mentioned areas, further investigations and systematic censuses are therefore needed in the coming springs.

Results from the monitoring programs of the Swiss Ornithological Institute show that the breeding populations of several forest species for which deadwood is an important habitat element (black woodpecker, great spotted woodpecker, middle spotted woodpecker, lesser spotted woodpecker, green woodpecker, three-toed woodpecker as well as crested tit, willow tit and Eurasian tree creeper) have increased in the period 1990 to 2008, although not to the same extent in all species. At the same time the white-backed woodpecker extended its range in eastern Switzerland. The Swiss National Forest Inventory shows an increase in the amount of deadwood in forests for the same period. For all the mentioned species, with the exception of green and middle spotted woodpecker, the growing availability of deadwood is likely to be the most important factor explaining this population increase.

Evolutionary dynamics of the Middle Spotted Woodpecker and the oak in the Canton of Vaud In the Canton of Vaud, the Middle Spotted Woodpecker (Dendrocopos medius) has shown a considerable increase in population over recent decades: in 2015, there were about 170 nesting territories. A census of the woodpecker, by its song, and a dendrometric inventory, taken together, made it possible to map the forest environment favourable to this bird, and to estimate present trends. Standing volume of oak in territories occupied by the Middle Spotted Woodpecker is, on average 124 m3/ha, of a total standing volume of 302 m3/ha. In more than 90% of territories of the Middle Spotted Woodpecker, standing volume of conifers is less 150 m3/ha, and of non-coniferous other than oak 269 m3/ha. These forests show a strong deficit in young stands capable of succeeding the mature oaks; this situation represents a long term threat to the oak and, as a result, to the populations of the Middle Spotted Woodpecker. A logical consequence of this situation is the need for a policy based on a strong political will to encourage oak-rich forests; the high genetic variability of the oak gives it an advantage compared to other species with regard to adaptation to climate change, but also with regard to the maintenance of biodiversity, the result of a heritage of several thousand years, of which the Middle Spotted Woodpecker is an integral part.

AbstractPaternal effort is high in some monogamous mating systems. Trivers' (1972) model predicts that high male investment in brood care should evolve only when males have a high certainty of paternity. For this study, we chose two woodpecker species: the great spotted woodpecker (Picoides major) and the middle spotted woodpecker (Picoides medius). Both species were socially monogamous despite a very high breeding density in the study area. We used DNA fingerprinting to determine whether these two species were also genetically monogamous. We found that in great spotted and middle spotted woodpeckers paternal effort was high. Multi-locus DNA-fingerprinting showed that its actual paternity was also very high. In P. major all 161 young from 36 broods and in P. medius all 61 young from 13 broods were sired by the male feeding at the nest hole. There were also no cases of intraspecific brood parasitism or quasi parasitism (P. major: 114 chicks from 24 broods; P.medius: 33 chicks from 8 broods). We further found no case of mate switching during the fertile period of the female. Great spotted and middle spotted woodpeckers are typical of a group of monogamous nonpasserine birds with high male investment in brood care having low frequencies of EPP. We did not find efficient paternity guards. High certainty of paternity may be explained by paternal care being essential for female reproductive success, as in many seabirds and birds of prey. Females rarely engage in extra-pair copulations probably because they are constrained by male care. Males in both species spend little effort in acquiring mates as well as in extrapair copulations. They expend their reproductive effort in defending territories and in parental care. Females compete intensely with members of their own sex for pair formation before the time of frequent copulation. Choosing and securing a high quality partner is the only possibility to achieve high reproductive success for both sexes.
