Nest failure in threatened #shorebirds has many reasons. Replacing eggs of vulnerable clutches with dummy eggs boosts nest survival of #Ruffs in grazed coastal meadows. New paper out 🎉 dx.doi.org/10.1002/ece3... in @ecol-evol.bsky.social #conservation #ornithology

This work was led by freshly celebrated PhD Hanna Algora with vital contributions from @koivulakari.bsky.social @vmpakanen.bsky.social @jellybb.bsky.social, Kriszti Kupán and others

#Tinttimetsä hanke julkaisee seitsemän videota metsätiaisista. Ensimmäisessä videossa tutustumme metsätiaisten elinympäristöihin Oulun yliopiston väitöskirjatutkija Satu Kumpulan kanssa. Käypä kurkkaamassa! www.youtube.com/watch?v=MVxa... @aksulehikoinen.bsky.social

#Tinttimetsä hankkeen neljännessä videossa kerrotaan, miten tehdään pökkelöpönttö hömö- ja töyhtötiaisille. Videolla yli 30 vuotta pökkelöpönttöjä metsiinsä laittanut metsänomistaja ja luontoharrastaja Juhani Kauppinen. Tää on aika hyvä! www.youtube.com/watch?v=WVL1... @aksulehikoinen.bsky.social

Kolmannessa #Tinttimetsä hankkeen videossa esittelen, miten metsätiaisten talvireviirejä voidaan säilyttää. En pahastu ollenkaan, jos et käy katsomassa 🫣. www.youtube.com/watch?v=d4G1... @aksulehikoinen.bsky.social

Incredibly warm March after such a cold Jan-Feb. The month will go down in history as the first March in Finland with nationwide mean temperature above freezing (0 °C). Practically all weather stations will set new March mean temperature record, except those located further out in the Baltic Sea.

Minulla oli ilo olla mukana ohjaamassa metsätalousinsinööri Kristiina Sillanpään opinnäytettä, jossa koottiin tutkimuskirjallisuus miten metsätaloustoimet vaikuttavat metsätiaisiin. Tämäkin työ on osa #Tinttimetsä -hankettamme. yle.fi/a/74-20210866 @nathist.bsky.social @helsinki.fi @metsakeskus.fi

Uusi kirjallisuuskatsaus kokoaa metsien käsittelyn negatiiviset vaikutukset metsätiaisten pesintään ja talvehtimiseen, mutta listaa myös ratkaisukeinoja miten tilannetta voidaan parantaa. www.epressi.com/tiedotteet/m... #hömötiainen #Tinttimetsä @metsakeskus.fi @nathist.bsky.social @helsinki.fi

5/5 In addition, a huge effort is made to protect the #critically #endangered southern #dunlin. With expertise of Vroni Rohr-Bender and others, 26 chicks got an advantage be growing up in our aviary, before they got released back in the meadows, hopefully successfully #boosting the #population.

4/5 Most time of the field season was spent searching for nests and to ringing the #chick and #adult ruffs. We found 65 nests in total which is an excellent result. Adult birds also got a radio or #GPStag to investigate #habitat use and behaviour. Aren't the chicks cute?

2/5: Fieldseason started in early May when the #ruffs arrived in the coastal meadows of the #BothnianBay. Male ruffs are known for their fascinating #lekking #behavior! A true spectacle! The existence of the different male morphs is unique.

3/5 Independent males have striking colours and are #aggressive. #Satellite males are mostly white coloured and have more #sneaky behavior. Female-looking faeders are extremely rare. Here an independent male is pecking a satellite to show its dominance. More: simonvandepitte.com/i-am-sexy-an...

1/5 - What.an.increadible.fieldseason! Together with @koivulakari.bsky.social , @jelenasubotic.bsky.social , @chorlnev.bsky.social , @vmpakanen.bsky.social, Kristzi Kupan, Vroni Rohr-Bender and others we managed to find plenty of ruff nests (65!) and headstarted a bunch of Southern Dunlins (26!).

Shorebird chicks are hatching here in Greenland! This year, egg predation has been intense, especially on Turnstone clutches, so every successful hatch feels extra special. This Turnstone male brooded its four chicks right next to my phone. A bit too close maybe...

There are now 148 blogs about waders/shorebirds in the WaderTales catalogue. Here's the list of what's available, with a short descriptor of each blog: wadertales.wordpress.com/about/ There are 14 blogs about (Eurasian) #Curlew, just to name one species. #ornithology

Oletko sinäkin kuullut sen valheen, että metsien ojittaminen olisi loppunut? Se on ajanpeluuta. Niin kauan kun ojitus on sallittua, se jatkuu koska aina löytyy joku joka hyötyy rahallisesti. Ojitus pitää kieltää lailla. Upea Ylen juttu aiheesta. yle.fi/a/74-20166276

Plenty of time to apply for this #postdoc in my group :) #genetics #microbiome #ecophysiology #evolution #avian #ECR

Intraclutch egg color variation in #ruffs is striking. Pale to strongly pigmented, speckled and not speckeled and even blue eggs within a single clutch 💙

Capture season at Liminganlahti. When we ring the #ruff chicks, we can often also catch their mums. Reeves (female ruffs) lead a very secret life. Thanks to our long term monitoring we learned that many return to breed in the next year to the same meadow.

Ruff lekking: The co-display of a pale satellite and a court-defending independent morph increases male attractiveness. Lekking began here (65°N) in the first week of May and continues, even though most females are already incubating and the first chicks are expected to hatch any day now.

Yesterday, we found the nest of this blonde female. Three of her eggs were also exceptionally pale. #ornithology #waders

A female Ruff enters her nest — a tent-like shelter hiding her precious eggs. She’s unringed for now, but she’ll receive her bands once the chicks hatch. #waders #ornithology

Important Ruff research. Flooding is becoming an increasing problem for Ruff & Dunlin: www.sciencedirect.com/science/arti... Blog about Dunlin-focused research @vmpakanen.bsky.social & @koivulakari.bsky.social wadertales.wordpress.com/2021/06/20/d... #ornithology

Ruff clutches are expertly hidden, the eggs are camouflaged and very difficult to find. But this year’s field crew with @jellybb.bsky.social @simonvandepitte.bsky.social @koivulakari.bsky.social @vmpakanen.bsky.social is on 🔥 and found already plenty of them.

The Finnish Dunlins are getting a Headstart. Over the next days we are expecting more than 20 🐣. Raising 🐥🐥is a huge effort, helped by our experiences we made with our captive ruff flock @mpiforbi.bsky.social

Shout out to Vroni Rohr-Bender for being an exceptional chick mum 🐣

It's a year of #headstarting for #BalticDunlins! First chicks are hatching and many more are on the way. We're trying to recover the almost extinct population breeding in coastal meadows around the #BothnianBay. Pics by Gerrit Wehrenberg @koivulakari.bsky.social @vmpakanen.bsky.social

Opera buffa? No, actually ruff male is dead serious in attracting females flying by to land at his lek. #waders #ornithology

FAO all those involved in tracking shorebirds. Please see this new Wadertales blog on the value of making these data (provided to us by the birds) available for current and future research: wadertales.wordpress.com/2025/05/06/m... www.globalwader.org #ornithology

Latest WaderTales blog reviews what we are learning from tracked waders/shorebirds: wadertales.wordpress.com/2025/05/06/m... But are researchers making full use of the data that birds collect for them? #ConservationScience🌍

Schinzii Dunlin are returning to Iceland (from W Africa). Species is in rapid decline: wadertales.wordpress.com/2025/02/20/i... Also disappearing from the Baltic: wadertales.wordpress.com/2021/06/20/d... Recently red-listed in the UK: wadertales.wordpress.com/2022/10/04/u... #ornithology

Yesterday's news that an Oystercatcher had broken the British/Irish longevity record for a wader (now 43 years from ringing to latest capture) is eye-catching but using ring reports to generate survival estimates is more important. wadertales.wordpress.com/2018/01/16/w... #ConservationScience🌍

Metsähallitus on hakannut n. 40 hehtaarin avohakkuun metsäpeurakankaalle. Kyseinen alue sijaitsee suoraan metsäpeurojen vaellusreitillä Sotkamon talvilaitumilta itään ja peurat kulkevat usein tästä ruokaillen samalla. Mahdollisuudet heikkenivät rajusti. Kuhmo, Hanhikangas 30.3.2025.

Valikoiva hakkuu eli metsien #jatkuvakasvatus on ilmastollisesti järkevää turvepohjaisissa kuusimetsissä.

#TIMBER! Finnish PM #petteriorpo government committed to protect the state's #natural & #OldGrowth forests. He broke the promise. The Orpo gov. tuned the criteria so strict, that most of the valuable old & natural forests are left without #protection! #Finnish #forestry #scam yle.fi/a/74-20150836

Epäuskottavaa suojelua. Sitä hallitus tarjoili tänään, kun se hyväksyi viimein vanhojen metsien suojelun kriteerit. Ne jättävät ison osan suojelemattomista arvometsistä hakkuiden armoille – hallituksen päätöksellä. #metsät #vanhatmetsät #luonnonsuojelu www.sll.fi/ajankohtaist...

1. Petteri Orpo petti lupauksensa. Piti laatia riippumattomat kriteerit, joiden nojalla loputkin valtion vanhat metsät saadaan turvaan. Ei tullut riippumattomia. Tuli kriteerit, jotka SYKE:n mukaan ovat "tieteellisen tiedon tarkoitushakuista vääristelyä". 2/
