- Aim of study: This study was carried out to determine the effects and importance of urban cemeteries on bird species diversity. Area of study: The Tepeoren cemetery is one of the oldest and most historically important cemeteries in the Istanbul region. Material and methods: Field studies of birds were carried out between April-September 2018/2019. During the study period of 12 months, the cemetery was visited twice a month. The species list of the area was created by registering all feeding, lodging, roosting and nesting birds observed in the area. Main results: It was determined that 36 bird species occured in the cemetery, out of which ten species were identified as breeding in the area. The main bird species that used the cemetery as breeding ground, was Corvus monedula (Western jackdaw) that utilizes the cavities of old oaks for nesting. The average number of eggs per nest was found to be 4.3 based on the examination of 49 active nests in 2018-2019. The number of fledged birds per nest was determined as 1.1. Higlights: In the current study, the importance of the city cemeteries in terms of bird diversity has been revealed. The presence of plant species that provide suitable nesting conditions for the reproduction of birds in these cemeteries supports the survival of the birds in the city.

- We used three woodpecker species as umbrella species for old deciduous forests, andanalysed their preferences in an area with old pollarded oaks in the Taurus Mountains,Turkey. Using plot inventories, we physically characterised trees utilised fornesting and foraging amongst woodpeckers in general and the Middle SpottedWoodpecker (Leiopicus medius) in particular. Trees more frequently visited by foragingwoodpeckers differed from randomly chosen trees by being taller, having alarger circumference, greater bark furrow depth and shorter distance to neighbouringtrees. Nesting trees were taller, had a higher proportion of dead wood but a lower surfacearea of natural cavities. Our results suggest that the woodpeckers in the study arearely upon woodlands containing mature trees, thus have the potential to functionas suitable umbrella species’ to highlight the conservation value of oak forest habitatsin southern Turkey.

- The Mediterranean basin exhibits a multitude of forest habitats affected by former and current exploitation and management. Recent afforestation programs have resulted in an increase in the proportion of coniferous trees, while oak stands, formerly utilized for coppicing and grazing, are abandoned or converted into coniferous plantations. The loss of oak stands might negatively affect birds dependent upon broadleaved forests. Studies confirming or rejecting that statement are scarce, particularly in the eastern part of the region. Using a study area in southwestern Turkey we applied a guild-based approach to investigate how pine and oak stands across a chronosequence differ in their capacity to support forest bird assemblages. Variables describing the vegetation were sampled to characterize the stands and relate bird assemblages to stand structure. Bird abundance and species richness was positively associated with age for both stand types. Richness and diversity was highest in oak stands, while there were no differences in bird abundance between the two forest types. Pine stands supported a different bird species composition compared to oak stands of the same age. Stand age and structure, rather than forest type, held the highest explanatory powers for bird assembly structure. Primary cavity-nesters and ground-nesters were more abundant in oak stands, possibly reflecting differences in stand structure and resource distribution. To support these birds with suitable habitats, oaks stands need conservation. Management practices in pine stands should strive for increasing the amount of old trees and retain vegetation in the understory to benefit breeding birds.
