Herbert Park pair have finally hatched 3 cygnets. Female (YN[CFKD]) is very young, hatched 2023. Hopefully they will do well. 🤞 #DublinSwans #Cygnets 🇮🇪

Monster swan! In 2019 I ringed a large cygnet. 10.5kg and wing cord 616mm. It lost its coloured ring in 2022 so re-trapped and then 13kg / 646mm. A chip was noticed on the Darvic last week so re-trapped. Now its 13.36kg / 656mm. We had to measure it twice!

#SandwichTern appeared today in Dun Laoghaire, Dublin. 🇮🇪 This one is from Northern Ireland, now heading south, probably down the African coast.

Tonight I recorded #HerringGull L60:D on a roof in Tallaght 🇮🇪. Not new to 2025 stats, as I recorded it on Lambay 30km away in June! #TeamGull

In Dublin 🇮🇪 the Common & Arctic Terns have fledged. The Juveniles sit on the rocks waiting for parents to feed. An opportunity for some ring reading.

All change in the Gull world. Dublin 🇮🇪. Large gull chicks mainly all fledged, starting to disperse and the number of small gulls increasing like these #MediterraneanGull from France 🇫🇷 and the Netherlands 🇳🇱. Here for Winter!

Found a post breeding roost in Tallaght last night 🇮🇪. 😀 100's of adult #LesserBlackBackedGull & 4 with our colour rings. They'll migrate soon, so fantastic to get the sightings. #TeamGull

Mopping up! The end of nesting season gives adults time to rest on the lampposts of Tallaght, Dublin. 🇮🇪. This #LesserBlackBackedGull was ringed as a nesting adult in 2023. Haven't found its nest site since but record it last year, same lamppost. #TeamGull #ColourRinging

Also at Seapoint, Dublin 🇮🇪 yesterday, Fledged Juvenile Terns being fed by parents. There are both Common & Arctic Terns in the flocks. (I'm sure there are probably Roseate Terns, but I didn't spot any). #TeamGull

Seabird watching - big changes. Gulls & Terns now leaving and arriving in Dublin. 🇮🇪. Selection of #MediterraneanGull from Seapoint yesterday. Already back in Ireland after nesting on the continent. #TeamGull

Up and down the Liffey Dublin. 🇮🇪. Looking for birds with #ColourRinging . Two #HerringGull missing since 2019 showed up and an angry Swan. #TeamGull #DublinSwans

Having issues getting an ID on this Fungus seen last weekend. Dublin 🇮🇪. Any experts that could give me a positive ID. 225mm tall (9"), Tennis ball size. Can't find a match in my book of common species.🤞

Received the history on this bird today. Ringed as a re-hab chick in 2014 in Cardiff 🏴󠁧󠁢󠁷󠁬󠁳󠁿. Only 2nd sighting in 11 years! #GowerRingingGroup

Out looking for our project #LesserBlackBackedGull. Eventually I did find a #ColourRinged one, but not #Dublin 🇮🇪 from #Swansea 🏴󠁧󠁢󠁷󠁬󠁳󠁿. Ring in terrible condition so hoping it's really old with lots of history. #TeamGull

We ring quite a few #LesserBlackBackedGull but don't get many resightings back in Ireland. This one was ringed in 2023 in Clondalkin and in the heavy rain this evening was at @TCSTallaght. Only one record from 2023, seen in Cork on migration to Iberia or Africa. #TeamGull

Swan Nesting survey almost complete, with just a few nests still to hatch. 🇮🇪🦢 Always also looking for our Gulls. Four recorded today at #GrangeCastleBusinessPark and 2 were new for 2025 data. #TeamGull

A bit surprised this moorning as P29:D was only 20km from Lambay. This afternoon saw #HerringGull P91:D @TCSTallaght . Distance of 30km+ which is more normal dispersal distance. Last sighting was in Arklow, so it hasn't yet settled. #TeamGull

#PoppintreePark Cygnets were out on the lake. Two had hatched last Sunday, but all 8 now hatched. Female obliged by showing her #ColourRing. The pen pulled up pond weed and a ball of fluff ensued as they ate it. Wonderful. @DubCityCouncil #DublinSwans 🇮🇪
