Cirl Bunting (Emberiza cirlus)

Posted by Rossen


The Cirl Bunting (Emberiza cirlus), is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae. It breeds across southern Europe, on the Mediterranean islands and in north Africa. It is a resident of these warmer areas, and does not migrate in winter. It is common in all sorts of open areas with some scrub or trees, but has a preference for sunny slopes.

Balkan Chamois in winter

Posted by Rossen


In Bulgaria Balkan Chamois occurs steep slopes with rock formations in Rila, Pirin, Slavianka, Vitosha, Balkan and Rhodope Mountains of about 600 to 2900 m asl. Despite the ban on hunting in many places the stock of chamois remains unsatisfactory. According Hristovich (1939) in Bulgaria has about 1,000 individuals: Rila - 600-700, Rhodopes - 150-200, Pirin 80-100 and Stara Planina about 100 (Petrov, 1965).

In winter Balkan Chamois are adapted to tolerate the harsh conditions in the high mountains, but sometimes falls victim to severe cold, deep snow, avalanches and landslides. The most common causes for winter mortality is poor food under the snow cover, whereupon the goats can not satisfy its energy needs. In winter goats are found in places where snow is blown or blown away by an avalanche, but in these places are usually in low windy days. There are large differences in preferred locations in quiet and windy days.This also applies to the wooded areas. Obviously, in order to avoid energy loss from strong cooling of the wind, do not visit the windy places with available food. This leads to a concentration of goats less windy places, but with worse food base. Besides food, the major factor in selecting a habitat is the temperature regime.In winter chamois prefer warm and sunny places.

Mid-winter Waterfowl Census 2014

Posted by Rossen



This year, for the Census of wintering waterfowl birds were identified days from 17th until 19th of January. Activity counting and data processing is coordinated by state institutions with the partnership of NGOs and the participation of others is voluntary. As expected, warmer winter influenced the number and species diversity of wintering waterfowl and other species associated with wetlands. In cloudy weather and a temperature of +11°C were recorded following birds observed in Blagoevgrad wetlands.
