165. Preserving an obscure bird: achievements and future challenges of Corncrake (Crex crexLinnaeus, 1758) conservation in Hungary

Abstract

The Corncrake is a strictly protected species in Hungary and a qualifying species of many Natura2000 sites. Despite its Least concern global conservation status, it receives much attention and was elected as “Bird of the Year” by MME BirdLife Hungary in 2016. In this paper, we estimate its population trends and analyse the suitability of the protected area system and agri-environment schemes for the species. We compiled information on major threatening factors and conservation measures applied for the species. We reviewed international publications on the ecology and conservation management of the species to extract information for practical conservation. We estimated that 500–2000 pairs of Corncrakes breed in Hungary. Although their breeding sites are well covered by protected areas, Natura2000 sites (42%) and High Nature Value Areas (67%), their population has declined by 55% over the last 20 years. We found that most of the major threatening factors are addressed by conservation management, and appropriate measures are applied in most cases. Recent research findings and recommendations by the BirdLife International Corncrake Conservation Team suggest that mowing of grasslands around nesting places should be delayed until 1–15 August either in the entire field or at least on 2 hectares around nests. Prescriptions of agri-environment schemes should also be adjusted to the above requirements and more farmers should be encouraged to enrol in Corncrake conservation programmes. We strongly suggest that more emphasis should be devoted to combat important threats for the most important breeding sites such as aridification and flooding.

198. The status of the Hoopoe (Upupa epops)in Hungary: a review

Author

Halmos, Gergő, Nagy, Károly, Karcza, Zsolt, and Szép, Tibor

Abstract

The Hoopoe is a widespread species in Hungary with the strongest populations on the Great plains. The fact that in 2015 it became ‛The Bird of the Year’ in Hungary offers the possibility to summarise the information about the distribution, population size, dispersion, migration as well as the nature conservation status of the Hoopoe population breeding in Hungary. In the period of 1999–2014 the number of breeding pairs and trend of population level was estimated based on the Common Bird Census database. The population size was estimated as 13,500–17,500 pairs with a stable trend (slope=−1.3%, SE=2.5%) over 1999–2014. There is very limited information on migration from bird ringing, only 8 recoveries between 1928–1963 indicate, that the Hungarian population is migrating on a south-southeast direction in autumn, wintering in the eastern parts of the Sahel, possibly in Chad and Sudan and migrates back in spring following a loop migration pattern further to the east. The main conservation issues are agricultural intensification impacting feeding possibilities, lack of nesting cavities and hunting during migration.
