Two retrapped Willow Tits at one of our sites this morning, in all likelihood a newly formed pair. The female (right) is an adult from one of the nests we were monitoring last year on the site. She lost her partner midway though egg-laying, presumably predated, but managed to fledge all four… (1/2)

Mental experiment: what would be the political reaction in Europe if 10000 Europeans were killed within a week by a terrorist oragnisation? How can the climate and ecosystems crisis still be treated as a non-issue, a niche concern, or nice to have?

Four juvenile Willow Tits colour ringed this morning at Wigan Flashes LNR, likely all part of the same brood. They should be dispersing soon, so fingers crossed for some follow up sightings, and maybe even nest finding next year… #UKBirding

The last Willow Tit nest of the season now fledged, successfully protected from Great Spotted Woodpecker predation. No GSW predation in protected nests this year, in stark contrast to 100% predation rate by GSW in unprotected nests. Very promising results.

After the completion of the bulk of Willow Tit fieldwork for the season, nice to have a change of scene helping out with a friend and fellow PhD student’s project on Sand Martins. Gorgeous birds, also joined by a few friends… #UKBirding

Probably the most stable stronghold of Willow Tits remaining in the northwest and a vital source population for surrounding areas. Sadly at least two traditional territories lost to urban development in the last couple of years, hoping AB can advocate for more robust legal protection for WTs…

Andy Burnham is now MP for an important constituency of Willow Tits! Key areas of Amberswood Common and the Flashes of Wigan & Leigh NNR are in Makerfield, where our study was based. There's dozens of Willow Tit territories there, and likely hundreds in the wider area. doi.org/10.1080/0006...

Willow Tit territories (and dots showing nests) in an area of Makerfield, Wigan.

Over several days, a male Great Spotted Woodpecker has spent more than 8 minutes trying to open up this protected Willow Tit nest. No way into this cavity! Protective mesh guard holding strong.

The last few days in the nest are a dangerous time for Willow Tit nestlings, their constant loud begging calls giving away their location. On this occasion they attracted the attention of a Tawny Owl, which tried its luck as one of the nestlings was calling from the entrance. This was a close call!

This male Willow Tit is a Superdad! Last year he permanently injured his leg fighting off a GSW when his nestlings were about to fledge. It’s been wonderful to follow him this year all season, now caring for his 7 nestlings almost ready to fledge. Good luck to him and his family!

Lesson in rewilding from an abandoned field in Carmarthenshire - Willow, Oak, Hawthorn, Bramble racing through the grasses. No habitat management plan, no livestock, no fences, no cost. Willow Tit singing at the bottom of the field. #EarthDay

Managed to spend a few hours this week watching a pair of our Willow Tits bringing a variety of food items to the nest. Mainly caterpillars, but also many spiders, aphids and craneflies. A balanced diet keeping the full brood healthy so far, and should be fledging in the next few days... #UKBirding

Extensive, unmanaged woodland habitats, abundant deadwood and understorey layer, good connectivity at a landscape scale, a paradise for Willow Tits. But there’s trouble in paradise. Another territory checked just a day too late. GSW predation hitting hard in Carmarthenshire.

A clutch of 8 eggs were hatching when a GSW attacked and killed 4 nestlings and the remaining 4 eggs were abandoned. The nest hole has been enlarged by the woodpecker.

For 7 days, a pair of Great Spotted Woodpecker kept a close eye on this Willow Tit nest. The male GSW took 3 minutes to destroy it. The clutch of 9 eggs were left by the GSW and abandoned by the Willow Tits. It’s touch and go if the WTs have a last nesting attempt this season…

Blue Tits are a problem for Willow Tits, often taking over WT nest cavities by aggressive eviction. With 6 WT eggs inside, these BTs spent an entire day removing nesting material! The second day was full on warfare, ending in successful WTs. Now a full clutch of 8 eggs safely under incubation. Phew!
