Roost ringing and 2 French Sedgies

A control juvenile Swallow was among the 30 caught last night on the Teifi Marsh. It will be interesting to see where a bird with the ring from the series Z907 was ringed, obviously very recently.

We now have 4 trainees and with a keen Biology student home for the holidays from Oxford Uni as well it was good to be able to introduce some of them to roost ringing in the reed bed.

Every evening from about 20.30 the numbers of Hirundines over the marsh builds to several hundred. This month we have caught 65 Swallows and 1 Sand Martin.

Pied Wagtails come in to roost a bit earlier and 19 have been ringed so far this month.

As usual we are out ringing early every morning, weather permitting, to continue our long term monitoring of migration through the Teifi Marsh. Sedge Warbler numbers are increasing and a surprise earlier in the week was a French control. Although we catch several French ringed birds in Spring, it was our first in July but this year this was swiftly followed by another French control, this time with a Strasbourg not Paris ring.
