Juveniles - Trigrad, Bulgaria - June 2007
|
| Tree Sparrows are generally common throughout their extensive range (Europe and Asia), but in Britain have suffered a drastic decline with their numbers dropping by about 90% between 1969 and 1994. Their numbers, however, do appear to have stabilised over the last 10 years and recent reports suggest they may even have increased slightly. |
