2019 Belvide Ringing Report


The 2019 Belvide Ringing Report
Overview:
A great year!! This is the first complete year when our ringing group has adopted the name Belvide Ringers as a sign of our commitment to Belvide. It made it even sweeter then, that 2019 was yet another record breaking year for the Belvide ringing project. We ringed more individual birds during the late summer/post breeding season than in any previous year. An unexpected new species in the form of a couple of Linnets increased the total species ringed at the site to 68 !!
Background:
It’s really fascinating to witness the year-on-year changes in the numbers and species ringed at Belvide. We can often only conjecture about the reasons why these changes occur—although with some species we can be a little more certain (see later).
Roger Clay’s operation at the West End continues to work well, and continued habitat work should result in increased totals as the years move on. This year he contributed 469 new birds. Within this there are some really fascinating differences from the main area—almost twice as many Blackbirds, SEVEN times the number of Song Thrush, half the Long Tailed Tits and an equal number of Bullfinch. To put these figures into context, Roger manages significantly fewer sessions due to work commitments, and only about a quarter of the total of nets. All of which points to the West End operation playing a great part in providing a much more complete picture of the birds at Belvide.
The two factors which appear to have the biggest influence on breeding success at Belvide are weather conditions during the breeding season, and the available habitat for nesting. Overall the weather was pretty good but yet again the water levels were very high until late in the season which inhibits reed growth thereby slowing down Reed Warbler breeding—as well as reducing the available nesting habitat for Sedge Warblers.
The weather during the ringing season was very good, good numbers of ringers were available and no sessions were lost—added to which passage was good with a constant movement of new birds through the site from quite an early date.

Discussion Points:
There are many possible areas for discussion but the main ones are:-
--the stand out figure is the number of Blackcaps ringed (861), which is almost three times the previous record. This mirrors reports from other ringing stations in the country and was mainly a result of early arrival followed by successful breeding. Indeed, in September we were catching young birds with newly fledged type plumage, suggesting that many Blackcaps certainly had two broods and several possibly three!
 
-- Reed and Sedge Warblers had good totals but our feeling is that their numbers really picked up once migration started suggesting the water levels did reduce breeding success on site.
--less regularly caught warblers such as Lesser and Common Whitethroats appear to at least be holding their own after several years of low numbers
--local breeders, such as tits, Wren, Dunnock, etc all have had at least a reasonable and in some cases very good breeding seasons linked to the generally good weather.
--the low numbers of hirundines is more a reflection of the good weather during the ringing period –we catch big numbers when there are cold and damp conditions
--the high number of Starlings reflects the increased effort put in to ring these.
Reports of Ringed birds:
Despite records in newly ringed birds, the number of birds we ringed which were reported elsewhere was disappointingly low.
Others may come through , but as a write we have had only 5 reports of our ringed birds-all Sedge Warblers, and all from the various well known ringing sites in the big estuaries through northern and mid France. These reinforce what we already know about the route and speed of movement of our birds so I have not repeated the same type of data from these recoveries that I have included in previous reports.
We have had some reports of the 115 nestling Black Headed Gulls we ringed but these will be reported when we produce a report specifically on that project.
Finally, we ringed only 4 Common Tern chicks this year with both metal and colour rings, which enabled someone birding at Crosby Marina to spot one of those tern chicks as it dispersed from Belvide. Interestingly it moved north—before presumably heading south for the winter. We hope that in future years we will be able to ring more tern chicks and thereby produce a report on their dispersal and possible return to their natal colony.
STOP PRESS- we have a report of one of our Sedge Warblers found in Mauritania !! In case you’re not quite sure where that is—if you find Morocco, travel south through Western Sahara, then you get to Mauritania. This is our most distant recovery of a Sedge Warbler and another piece in the jigsaw of where these birds travel to spend the winter.
This juvenile bird ( hatched probably at Belvide in early July)—was ringed on 8th August at Belvide, and was controlled by a ringer in Mauritania on the 9th February 2019 – a distance of 4226 kilometers from Belvide. This is an interesting date—was this bird spending the winter in Mauritania, or had is started it’s northward migration back ‘home’? These questions will be much easier to answer when we are able to fit real time data loggers on to these small birds and track them in detail. For now though- a great record!
                        
In conclusion:
It’s only by concerted teamwork that an operation like ours can be successful. Most obviously we rely on our team of ringers to be available for what is a considerable time commitment over three months—thanks team.
However, there are many others we would like to thank:-
-- the committee of the West Midland Bird Club give us permission to ring on the site, and their moral support throughout is invaluable,
-- the Belvide management team provide lots of support, from calling in when we are ringing to see how things are going—to helping prepare the ringing site during the annual work party programme, their banter is always a welcome addition to our ringing sessions!!
--our dear friend Gladys Chappell is no longer with us but her support for our gull and other studies is still much appreciated,
--the many WMBC members who stop by at out our sessions and show interest probably don’t fully realise how much we appreciate their interest.
To all of those above we say a sincere THANK YOU, and hope to see you all again in 2020.
