Wheatear number 8979876 Five years old male wheatear, ringed at Lista May 2007. Spring 2012: a reunion with 8979876 and continued positive trend for chiffchaff and blackcap
By M. Wold One of the things we gain knowledge about from ringing birds, is their life span. Wheatear number 8979876 was ringed as a chick at Lista Bird Observatory in July 2007. Three years after, on May 19th, it was retrapped at the observatory, and again on May 11 this year. It is now five years old, and has flown the distance Africa - Lista a number times. Ringing numbers spring 2012A total of 1221 birds were ringed during spring season 2012. The table below shows the numbers for the ten most common birds this season, compared to the numbers from spring 2011. Robin is on top with 194 new birds ringed. This is quite a high number compared to the 61 robins ringed during the same period last year, and well above the average for the last 23 years. Blackbird experienced an all-time low since 1990 with only 44 new birds ringed, half of the 23-year average of 88 birds. These variations are nevertheless completely in line with the expected yearly variations for these species. A notable thing from last autumn was the unusual high numbers of chiffchaffs. This seems to continue into spring season, about twice as many birds were ringed this spring compared to spring 2011. Fig. 1 shows the number of ringed chiffchaffs, and the last 10 years seem to have been a good period for chiffchaffs. Another species that seems to have a positive long-term trend is blackcap. Fig. 2 shows the ringing numbers over the last 23 years, and apart from the yearly variations, there is a notable positive trend.
The bird observatory has a summer break during breeding season, and opens again on July 15th. | ||||||||||||||||||||||||||||||||||||||||||
