Dagens arbete:

Two new nests of Great Reed Warbler were found today, which is unusually late in the season.

In the Farmland Survey, Marianne learned that the chicks in the new Skylark nest she found had fledged already and thus couldn’t be trapped at the nest for ringing and sample taking. The Ortolan female who nested behind the house is still hanging around and has been seen a few times, but we are more interested in her male, whom we sadly haven’t been able to locate lately. We’re also a tad worried about her chicks, which we have still to observe, although the parents did seem to be feeding fledged chicks a little while ago. Could they have been predated? Fingers crossed that they haven’t, but we’re really starting to wonder…


The Marsh Harrier nest ringing project is now ended, with 15 chicks ringed in eight different nests. We also found one dead chick – an entirely normal part of a raptor nest, as only one or two of the chicks usually survive. In two of the nests, the chicks had fledged (more or less – they climb around the reeds for a while before properly fledging). Two of the nests were empty and four contained chicks that had not yet fledged. We’ve now proudly signed our initials on the ringing sheets of size 8 rings, being one of the teams that have helped monitor the impressive Marsh Harrier population around Kvismaren. Peace, over and out from Lt. Dan (our reed-walking pole) & Co.!

Tonight, there was also an impressively dense population of Homo Sapiens on Ängfallet: 12 people came for dinner, and Marianne made lasagna for all of us. It was – as usual – very tasty!

CES: Ringing today took place at Vallen. We caught an easily manageable amount of birds, and had enough time to carefully study the ones we found interesting. The summary of today’s catch is as follows:

Sedge Warbler: 7 ringed, 3 retraps               = 10

Reed Warbler: 17 ringed, 10 retraps            = 27

Icterine Warbler: 2 ringed                           = 02

Willow Warbler: 3 ringed, 2 retraps            = 05

Reed Bunting: 17 ringed, 4 retraps             = 21

Common Whitethroat: 5 ringed, 7 retraps = 12

Blackcap: 1 ringed                                       = 01

Garden Warbler: 4 ringed                           = 04

Thrush Nightingale: 2 ringed, 3 retraps      = 05

Bluetit: 2 retraps                                        = 02

In total: 89 birds of 10 species. 31 of these were retraps and 58 were new ringings.
