Breeding bird survey in western Azerbaijan


Text & Photos © Max Baumgarten 

My name is Max and I study Biodiversity and Ecology (M.Sc.) at Greifswald University (Germany). I am currently conducting the field work in Azerbaijan for my master thesis with the title 'The breeding bird communities of the western parts of Azerbaijan and their response to human alteration'. In the first two weeks (in April) I tried to get an overview of the study area, which stretches from the Lesser to the Greater Caucasus. In the beginning of my field work I focused on the ‘early’ species, such as woodpeckers, tits and other resident birds. Most of these species are found in forests and mapping them sometimes proofed to be difficult as most forested areas are on steep slopes and far away from any infrastructure. In general, most accessible places outside protected areas, either forests or steppe habitats, are unfortunately grazed or otherwise used and finding more natural places appears to be difficult. Nevertheless, the sampled forests hold almost all species known from home (Germany) including some additional goodies like Semi-collared Flycatchers or Booted Eagles.

Woodchat Shrikes arrived at the end of April
As forests cover only a fraction of the study area, I spent most of the time in agricultural land or in steppes. A cultural landscape, as every central European conservationist dreams of, is still present here on a large scale and sometimes it feels like a travel back in time. Thanks to this circumstance Rollers, Hoopoes, Quails, Motague's Harriers and other elsewhere rare farmland birds are a common sight and spending a day without seeing/hearing them is almost impossible.

Rollers are common, but Rollers on natural vegetation are rare

Among the breeding birds I was able to find new breeding pairs of rare breeders such as Lesser-spotted Eagle or Eastern Orphean Warbler. Maybe even the first breeding record of Common Crane  (Grus grus lilfordi) for the country? One bird was observed in Qarayazi State Reserve, on 29 April, which is very late for a migrating individual. Additionally, the bird was very small and only weakly coloured around the head that hints for the eastern subspecies lilfordi, which breeds in eastern Turkey.

Black Vultures can be encountered throughout the area
Besides my actual field work I always had an eye on bird migration, which took a while to start and is more obvious since mid-April. Nice species such as Black-winged Pratincoles, Pallid Harriers and up to five subspecies of Yellow Wagtails could be observed. Keeping an eye on the wagtails produced a presumed White-headed Yellow Wagtail (Motacilla flava leucocephala), which is a vagrant in the WP and only rarely recorded.
 
White-headed Yellow Wagtail or just a very pale beema?

Will this be a Rosy Starling Year?
The gathered data will not only be used for my master thesis, it will also be part of the European Breeding Bird Atlas (EBBA2), who support me during this expedition.

Stay tuned for what’s going on in the best month of the year!

Azerbaijan in eBird

Just recently a dataset of 30.000+ bird records from Azerbaijan has been uploaded to eBird and is now ready for getting explored! This online database provides an easy opportunity to prepare birding trips and find out what to expect. Nevertheless, there are still ornithological gaps of knowledge, so if you intend to visit Azerbaijan it would be fantastic if you could make your observations available, too!

Nocturnal bird migration data of Besh Barmag bottleneck


Text © Michael Heiß

Thanks to Gerard Troost and trektellen.nl the data of a nocturnal bird migration study from Besh Barmag bottleneck is now online available:


Displayed are the number of calls per species for each night, where 'night' is defined as timespan from sunset to sunrise. The temporal calling activity can be obtained by the ‘mouseover’ function of the table.

On the basis of 1465 hours of sound recordings referring to 63 nights in autumn 2011 and 67 nights in spring 2012 (using a long-term recorder from WildlifeAcoustics) a total of 88’455 calls of 106 migrating species were detected.


The paper with the title ‘Nocturnal bird migration at Besh Barmag bottleneck in Azerbaijan as revealed by means of acoustic monitoring‘ is online available: https://doi.org/10.1017/S0959270917000454
