Abstract:

Objective: Populations of passerine birds that migrate for long distances are decreasing continuously. In recent years, the declining trend of the population number of Rustic Bunting (Emberiza rustica) is more prominent. Through the long-term monitoring and migration dynamics analysis of the Rustic Bunting population, we intent to provide a scientific basis for the species conservation. Method: From 2001 to 2017, 70 pieces of sticky net with 3 m high and 20 m long were set up in different habitats from 15th March to 31th May and from 15th August to 20th November in Gaofeng forest region, Nenjiang, China. Patrol was implemented once every half an hour. The birds trapped in the net were recorded and then released after banding. Meteorological data were recorded daily from 2001 to 2017 by Nenjiang meteorological station which located 6 km away from Gaofeng forest region, and downloaded from the website of China meteorological data sharing service. Data were analyzed by SPSS 22.0 software. Result: From 2001 to 2017, a total of 18 155 Rustic Buntings were recorded and banded, including 6 756 Rustic Buntings in spring and 11 399 in autumn. The quantity of banding records fluctuated greatly annually, showing a rapid downward trend in general. The spring migration peak of Rustic Bunting was from 1st to 20th April, while the autumn migration peak was from late September to early October, and the ratio of adult to juvenile was 25.4:74.6 and 43.3:56.7 respectively in autumn and in the following spring. The overwintering loss rate of young birds was as high as 41.3% compared with that of adult birds. The correlation analysis between the quantity of bandings and meteorological factors showed that the maximum wind speed and wind direction were the main factors that dominated the migration direction and migration timing of Rustic Bunting. Recapture indicated that Northeast China is an important and relatively stable migration corridor for Rustic Bunting and other birds. Conclusion: In recent years, the population of Rustic Bunting has decreased sharply. The number of the birds banded decreased by more than 90% compared with the year with the largest number of banding, which is worthy of attention. Abuse of pesticides, surface water pollution, habitat fragmentation and illegal hunting are the main threats to the survival of Rustic Bunting. It is suggested that measures such as timely increasing law enforcement and propaganda, reasonably using high-efficiency, low toxicity and low residue pesticides, strengthening the protection of bird habitat, taking long-term bird banding monitoring, further exploring the rule of migration of Rustic Bunting, and promoting the recovering of bird populations.
