After adding Ross's Goose (ringed in Canada) last weekend and now a Lesser Scaup, the Ottenby area today reached the milestone of 400 observed bird species! 🍾🥂

April 1, 1980, still the only ringed Steller's Eider here at Ottenby. The Baltic Sea used to hold a wintering population of this arctic duck, but since 2000 we have seen a sharp decline, probably caused by a shift in wintering grounds due to warmer climate. Photo Staffan Bensch

A fine example of a 5M GGS at Ottenby this morning. Released with fingers intact (kinda)

We are happy to announce two new contributions to the Ringers Digiguide: Bohemian Waxwing and Eurasian Teal, both by Jaime Miralles de Imperial, the latter supplemented by Malva Rohman and Larissa Simulik.

Will never get sick of these 😍

One of many beauties in the lighthouse garden these days! #birdmigration #birdringing #birdbanding

motus.org moving forward with citizen science to new bird and bat migration discoveries #motusuk

Yet another cool #motus registration from our Yellow-browed Warblers! Trapped and tagged at #Ottenby on Sep 14 and then recorded on four different receivers around the German bight September 26-28, before disappearing into the Dutch inland. #birdmigration #animaltracking

Our first Siberian Chiffchaff for the autumn

Long-term data from Ottenby Bird Observatory is highly relevant also in a human context. Decades of sampling for zoonotic diseases with Linnéuniversitetet Linnaeus University combined with migration studies:

Two nice ones from the last days. A young Greenish Warbler and an adult male Common Redstart with rather extreme whitish pattern in the edges of the tertials and the inner secondaries.

Now switching to red… Many nice improvements with extended taxomony, updated biometrics etc.

New MOTUS tower just dropped at Torhamn, Blekinge. Hopefully it will pick up our birds leaving Ottenby Bird Observatory in the fall.

This morning marked the end of the spring season here at Ottenby! During one of the rounds we trapped a Blyth’s Reed Warbler together with its close relatives Common Reed and Marsh Warbler.

Yesterday evening a Paddyfield Warbler (Acrocephalus agricola) was trapped and ringed. This was the fifth record of the species for Ottenby.

New study out today in Ornis Svecica on changes in numbers and phenology of Little Stints at Ottenby Bird Observatory (@OttenbyBO), Sweden, over the last 75 years. doi.org/10.34080/os.v3…

A beautiful male Ortolan Bunting was trapped during the morning. This species has seen a severe and rapid decline during last decades and the annual average has gone from a handful to close to zero.

This morning we ringed a beautiful adult female Green woodpecker! Caught in one of our nets.

P.S. we're also on Instagram:

A good reminder that one should always go past the Helgoland trap when going to bed 🤩We catch only a handful of Tawny owls here every season, so every caught individual is quite special!
