Last Gulls of the Summer

We've reached the end of summer and the end of our gull darvics. The 250th was put on a Lesser Black-backed Gull today, after a whoosh net catch on Aberdeen beach. Time to order some new rings!

Most of the birds ringed over the summer have been Herring Gulls, but seven Lesser Black-backed Gull, two Greater Black-backed Gulls and a Glaucous Gull have also been colour ringed. The Glaucous is the first to be ringed in the UK since 2002, with only 60 birds having ever been ringed.

The first Greater Black-backed Gull (above) we colour ringed this year at Fraserburgh was seen 45 miles away at Lossiemouth 4 days later. Having only ringed two Greaters so far that's a good resighting rate! We intend to catch more this autumn at the harbours up north.

Several birds we caught had already been metal ringed. The oldest was ringed as a chick at Aberdeen harbour in 1997. Many gulls are now being resighted around the city. The photo below shows two juveniles we'd ringed at different sites standing right next to each other. Amazingly we'd only ringed three juveniles at that stage! From our resightings we are seeing that breeding birds don't necessarily feed near the nest site, with birds ringed in our gardens in the suburbs seen on rooftops 8 miles away in the city centre. Hopefully more resightings will help us understand more about the movements and population of Aberdeens gulls.

Please check all gulls you see for colour rings.

100th Gull Colour Ringed

We have been catching large gulls this summer around Aberdeen for a new colour ringing project, and caught our 100th bird today. This particular bird had all ready been metal ringed, by myself last summer. Like the majority of the birds we've ringed it was an adult Herring Gull. We have also ringed four adult Lesser Black-backed Gulls, and are now starting to catch this years juveniles as they come off the roofs. Most of the gulls have been caught by hand around the city, although some have also been clap netted in our gardens. Gulls are easisest to catch at this time of year, with juveniles fully grown yet still reliant on their parents for food, meaning adult gulls are more confident and reckless than usual. Hopefully we will ring a lot more before summer is over. Please check the gulls you see around Aberdeen for rings.

Colour Ringing Gulls

We have started a new colour ringing project: Herring Gulls (and Lesser and Greater Black-backed Gulls if we can get our hands on them). "The North East Scotland Gull project" as I've just decided to call it will see us putting colour rings on any large gull we catch in the Grampian and Tay area, with Ben Herschell from Tay Ringing Group colour ringing gulls in and around Montrose.
   We ringed our first birds today, caught by hand at a legendary site we refer to as "the magic fence." Hopefully they will be the first of many this summer, as we are soon getting to the period when gulls are easy to catch. They lose all caution and common sense when they have chicks, as they desperately try to secure Asda smart price bread for them

Catching at the Magic Fence - thanks to Keith Barker for sending us this photo Another bird caught later in the Burger King car park!

Please look out for our gulls, all have a yellow ring on the left leg, with the letter T followed by a colon and three numbers.

Scarce passage migrant twitch ringing!

We had a scarce passage migrant visitor mid week in the shape of Richie Hearn from WWT Slimbridge, always a welcome addition to the year's list. Last bird he ringed was red breasted goose in Bulgaria (and probably Brazilian Merganser in Brazil before that) so it was no wonder he was looking a bit glum when he was given some juvy linnet rtps to look at!

His face brightened up a bit when he was told there was a linnet brood needing ringing though.......a pullus ringing tick for him!

He dipped on mipit pullus (already ringed) and goldfinch and whitethroat which were too wee to ring.

We are onto the last of first brood linnets now and building well underway for 2nd broods. We had a nice example of 'rabbit syndrome' typical of some of these carduellis finches last week. As we approached a gorse bush containing a nest with c10 day old chicks we noticed the female arriving with nest material closely followed by the male. Once the female disappeared into her new nest (about a metre from the 1st nest) the male nipped over to the first nest to feed the chicks and came back over with a faecal sack in beak just in time to accompany the female away for more nest material........TOTALS!

More Girdleness-ting

Linties are now well on-stream with 11 broods ringed today, with our total now standing on 99 chicks. We have a similar number of titchy chicks that'll be for ringing next weekend. Few failures with their ring of gorse defence but same can’t be said for the ground nesting mipits and skylark with quite a few failures but 3 broods of mipos now ringed (below).
50th lintie nest was well found by Calum and appropriately marked with a Thornton’s Easter Bunny ribbon (see photos below).
We are used to finding goldfinch nests at the end of high sycamore branches in winter once the leaves are off the trees but at this site they have taken to using head high dog roses……..luvly (photo below). First brood ringed today and a further 2 on eggs. Some adults were clap netted as well as skylark and meadow pipits. We also got a control lintie……..L627288 Any takers?

Lintie nesting

Despite another cold snowy spell last winter our breeding linnet numbers seem to be buoyant and thriving, at least in their favourite habitat in the coastal gorse bushes. First 3 broods were ringed last weekend with another 30+ lined up for the next few weekends. Main threat is burning by vandals with one or two nests and favoured gorse clumps already gone. Our major stick twatting day to find all the nests we’d missed during building proved a bit disappointing with most female linnets sitting very tight in the cool and misty conditions (see photo above). Other nests included pied wagtail, blackbird chicks, a well sign posted goldfinch (see photo below), swallow building, a few meadow pipits and an early rock pipit with young chicks.

Top tip for finding meadow pipit nests: Stand in a group in the rough grass and yap for a few minutes……it eventually unnerves the sitting bird and it flutters off………2 found by this very skilful method!

Watch out for a photo of Rotti Man (The Viz ornithologist) next posting.

Ravens in Grampian

This week we also ringed a new species for the group – Raven. Although common in other parts of the country this species seems to be just starting to recover from the severe persecution they have suffered. A few pairs are now breeding in the region and this is the first brood to be ringed by the group. We have also heard recently of a golden eagle tracked by the RSPB, which was found poisoned in Glenbuchat in Strathdon, so there are obviously still individuals deliberately killing protected birds in our uplands. We wish our ravens chicks all the best and hope them a long happy life, unlike the poor golden eagle.
