Loess & Bee-eaters VI: the European Bee-eater (Merops apiaster) in Hungary... + the Loess in Hungary

Gyuracz, J., Nagy, K., Fuisz, T.I., Kareza, Zs., Szep, T.  2013.  European Bee-eater (Merops apiaster Linnaeus 1758) in Hungary: a review.  Ornis Hungarica 21, 1-22

Kerenyi, Z., Ivok, E.  2013.  Nestsite characteristics of the European Bee-eater (Merops apiaster L) in the Godollo Hills.  Ornis Hungarica 21, 23-32.

Urban, S., Turi, K., Vas, Z., Fuisz, T.I.,  2013.  A successful habitat reconstruction effort, the short history of the European Bee-eater (merops apiaster) colony at Albertirsa (Hungary).  Ornis Hungarica 21, 47-51.



Two maps: Fig.2 shows the distribution of bee-eaters in Hungary- from Gyuracz et al 2013 (the reference listed above); Loess Ground added the colour; its a beautiful and detailed map. The paper shows that there is more of Hungary to be studied from the bee-eater nesting point of view; fig.2 shows bee-eaters in the regions that have been studied.
Fig.4 is a rather less detailed and stylish map- its an old map, from Smalley & Leach 1978, and it hints at loess distribution in Hungary. S & L did not have access to a proper detailed loess map of Hungary; the regions D3 and D4 belong to the outline (emphasize outline) distribution of loess in the Danube Basin and related parts of East-Central Europe. In retrospect its a rather absurd description of the distribution of loess- but actually its not that bad.






Abb.8 is the slightly enhanced map of loess in Hungary from Scheidig 1934. The loess shown by Scheidig and the bee-eater zones of Gyuracz et al do show a good correlation. Hungary must be close to some sort of northern limit for bee-eater nesting; the reports of bee-eaters in Poland and the Czech Republic are not reports of large well established populations; in Hungary there are substantial numbers.

"The 27 colourful & morphologically uniform species of the Meropidae family are divided into 3 genera. The 3 species belonging to the Nyctiornis (2 species) and Meropogon (1 specie) genera are confined to the Far East, from the Himalayan Mountains to the Sulawesi; while the 24 species of the Merops genus can be divided into 2 biogeographical and ecological species clade on the basis of phylogenetic analysis.." (Gyuracz et al 2013)
