A is for August, acros...but not Aquatics

August ringing is over with another 14 new acros in the Mallard nets today. Our final August totals for 2013 compared to previous years.

Mallard nets only            Sedge   Reed   Aquatic Warblers
August 2013                    274      178
August 2012                    106        66
August 2011                    323        58 
August 2010                    265        94        2(two)

A huge increase in Reed Warblers...breeders or  passage....BUT no Aquatics, remember no confirmed breeding of Reed Warblers  in either Ceredigon or Pembs until the mid/late 1970's !

A map of the reserve showing showing the Mallard net runs (extended since this map) in relation to the CES site. The huge area around Mallard is mainly phragmites. To the north the phragmites is a commercial cut and very healthy growth.

The Teifi Marsh site - which includes CES, full year totals are as follows compared to previous years

Teifi Marsh             Sedge    Reed   Aquatic Warblers
 2013 to date            481       275
 2012                       226       166
 2011                       620       289 
 2010                       612       437        2(two)

In both 2010 and 2013, large numbers of passage Sedge Warblers were ringed in early May. 
(May 2010 - 175 Sedge Warblers ringed mainly on two dates)
In 2010 we ringed 222 Reed Warblers on the CES site.....this year only 54.....
A shift in the breeding population to quality reed growth or ....?

How we remember Mallard in the early morning....
Home in August......

A huge thanks to Wendy and Chris....all this data including today's (except 3 ringed tonight) is entered in IPMR..
