Totals, and the first juveniles appear

May ended with a Skokholm visit - more in a separate blog by Thom, on his first visit (see post below).... the re encounter of this Moltoni's Warbler was the highlight. The bird gave it's distinctive and diagnostic  call after release and a feather sample had been obtained previously.

Ringing totals - these are year to date following a large DemOn entry over the past week, some from earlier in the year..

The ringing totals for the first 6 months of the year ringing are slightly lower than the average for the last 6 years. Looking through the species, our main projects eg RAS and targeted ringing eg Woodcock are often discussed on this blog through the year as the seasons provides ongoing results.

A few species in the table that are worthy of further comment

House Sparrow ...see link to Andy's RAS study 

House Sparrow RAS update 

Linnets...Chris is working at a new site on the north Pembs coast, currently in development as a  RAS study and showing good potential, with 170 ringed recently.

The whoosh net for Linnets in place

Other species have also been ringed at this cliff top location including a very young Skylark and an adult, Grasshopper Warbler, Stonechat, Meadow Pipits and Dunnocks

Reed Warblers... an ongoing RAS study

One of our most important species for the reserve, with a great history,  captures a bit low so far this season with 27 so far from previous years. Here is an example of a Reed Warbler's life history ....

Richard Donaghey, Causeway Coast Ringing Group wrote a report on the Reed Warbler in Northern Ireland back in 2018 (see link below) including the migration routes, ringing recoveries to/from Ireland & recoveries of NI Sedge Warblers. 4 years on, the Reed Warbler has continued to spread across Ireland. 

In the report a Teifi Marsh Reed Warbler is mentioned because the recovery was one of several that helped plot the migration routes.

"Reed Warbler P351137 has a fantastic life history and shows a clear migration route with a nice sequence of recoveries. It was originally ringed as a juvenile in August 2000 in Arklow, Wicklow before heading off to sub-Saharan Africa for the winter. It returned north via Portland Bill Bird Observatory, Dorset on the 3rdof June 2001 before being trapped once again two days later in south-west Wales at the Teifi Marshes. This wasn’t the end of the story as it was recaptured back at its breeding site in Arklow seven days later and was retrapped there on a number of occasions right up until the 12th of August. "

Reed Buntings..an ongoing RAS study

We are very grateful to photographers visiting the reserve who send us record shots of colour-ringed birds.

Reed Bunting 

This female Reed Bunting from Michael Davey was ringed in July 2019 as a juvenile and seen several times each year since, usually near Mallard hide

Sedge Warblers... 

Sedge Warbler

300 new this Spring. On the peak migration days, we encountered a bird ringed elsewhere every day for 3 days. Few Sedge Warblers actually breed on our site, many more Reed Warblers do. 

Willow Tit...records including colour-ringed birds still to be entered. There is ongoing potential for a RAS study by Arfon on Cors Caron. 

 

Kevin Henderson has joined the Group having moved to the Pen Caer peninsular. He is already ringing in his garden and he has plans to set up a couple of sites in his local area as well as joining other group activities.

July brings us Storm Petrel ringing, the start of warbler migration, hirundine roost ringing as well as continuing our ringing projects. Usually this means increasing numbers of birds as this year's juveniles swell the population, and many of the juveniles are not from local populations - so hopefully plenty of activity for the group. 

Members of the group will also be visiting Skokholm Bird Observatory twice in July.
