Version 1.5 (12.1.2000)

This is a preliminary summary of all records of Radde's (Phylloscopus schwarzi) and Dusky Warbler (P. fuscatus) in Europe in autumn 1999.

Both species were recorded in good numbers in 1999, but the occurrence of Radde's was unprecedented.

All records in this article are subject to ratification by each country's respective records committee!

Radde's Warbler (Phylloscopus schwarzi)

A spectacular occurrence in Europe with about 56 individuals recorded between September 24 and October 31.

The first records were from the Fenno-Scandinavia as expected apart from one in Great Britain already in late September. From the October 6^th onwards the birds reached also Germany, the Netherlands, Poland (2^nd for the country) and more individuals were seen in Great Britain. Apparently new individuals appeared continuously from the east and the peak was reached around mid month when the first birds were also located in France. One bird also reached Malta on October 23 (2^nd for the country).

Remarks about the species' occurrence in Europe (including a phenology histogram of all records) can be found in Dierscke & McAdams (1990).

All records known to me are listed in the table below.

• The Estonian record is the first for the country if accepted!
• There is only one previous record for Radde's Warbler from Malta. One was trapped and ringed at Ghadira on 6 November 1990.
• The Polish record is the 2^nd for the country.
• There was only 10 previous records from Finland accepted by the Finnish RC until 1998. Thus, the seven (!) records in the above table is an unprecedented influx.

Dusky Warbler (Phylloscopus fuscatus)

The first (as many times before) sneaked through Fennoscandia undetected to Great Britain in late September. In the first half of October birds were also found in Fenno-Scandinavia (and Poland) (also one already in France on 3 October). After mid month birds more birds had reached Belgium, France and Great Britain. New individuals seemed to arrive through the month. The peak in Great Britain was in late October.
