The 2025 season is well and truly underway. Our long-term volunteers, Molly and Amy, have now settled into their duties and projects are well underway. Take a look at what they have been getting up to during late April and early May.
Spring has arrived! Watching Skomer Island gradually become a sea of bluebells and red campion has been truly magical. An influx of swallows has also solidified a change in the season and their sweet-chattery calls now fill the air at the farm.

The longer evenings and warmer weather have been a great excuse to get the Kubb out. A game enjoyed throughout the years on the island involving wooden blocks, throwing sticks, defensive lines and great distraction techniques!
As long term volunteers, Amy and I have thoroughly enjoyed spending time with the weekly volunteers. We have met some amazing people so far, connecting through our passion for nature and Pembrokeshire islands with long-standing and new volunteers. Card games have been a favourite!
The island team have given Amy and I two personal projects to complete during our time on Skomer. Firstly, I will be studying the island population of chough. In line with the Chough Conservation Strategy for Pembrokeshire and the Pembrokeshire Local Biodiversity Action Plan Species Action Plan for the chough, the project focuses on the number and distribution of breeding pairs and on productivity. Data collected on the sub-population of chough here on Skomer will contribute to a larger assessment of the conservation status of chough here in Wales.
Here is a summary of my findings during late April and early May:
- 10 pairs have been recorded around the island with a non-breeding group of 7 individuals moving between the island and mainland.
- 7 of these pairs have displayed breeding behaviour that indicates incubation of eggs.
- 1 pair has been seen taking an egg sac out of the nest, indicating hatching of chicks.
A hopeful year for chough so far, lets keep our fingers crossed that this continues throughout the rest of the breeding season!

Secondly, I will be studying the island population of Jackdaw. Jackdaws are difficult to census; new methodologies have been curated in hope to gain further understanding of the current status of Jackdaw on Skomer. The aims of the project include establishing the number of Jackdaws nesting on Skomer, mapping their breeding areas and calculating productivity from a sub-set of nests.
Here is a summary of my findings during late April and early May:
- Jackdaw colonies on Skomer are located at numerous locations around the island, of those surveyed so far colonies average at 20 pairs.
- Jackdaws are nest building enthusiasts and have been seen working hard consistently bringing nest material to nest sites over the whole duration of the survey period.
- Individuals have been seen feeding partners on the nest, an indication of incubation.
- In recent days, I have noted jackdaws carrying eggs shells out of nest sites, indicating hatching of chicks has begun.
The team on Skomer have been great with clear guidance, support and shared excitement when clear breeding behaviour is noted for both species!

We have been so lucky with the amazing warm sunny weather and lovely clear night skies, mid April we were treated to a brief but beautiful showing of the Northern lights. Pillars were visible to the naked eye as they danced across the sky.

Owl and curlew watches continue
The short eared owls have been out in force recently, appearing everywhere you look! With lots of territorial behaviour between them and with the curlew being very vocal and active too, it was time to do another evening watch to see if we could pin down any nest sites or territories. We all headed out in different directions to different viewpoints across the island recording what we saw and at what time.

The first razorbill and guillemot eggs
The seabirds have been busy arriving back on the island, pairing up and now, finally, the first signs of the next generation are here, the first precious eggs have been laid amongst the rocky crevices and ledges that these birds call home. The arrival of these first eggs shows that the breeding season is well underway and over the coming weeks more eggs will appear, painting the cliffs faces with their range in colours and blotchy patterns.

Raven chicks fledge!
Over the past few weeks we have watched closely as the raven chicks have rapidly grown, these intelligent charismatic corvids, known for their glossy black plumage and distinctive croaking calls, are now seeing their offspring leave the security of the nest and taking their first tentative flights.

Research projects
I have been lucky enough to have been given the research project of my favourite species on Skomer, razorbills, monitoring their productivity. These funky looking black and white auks return to the island in their thousands each spring to breed, and understanding their breeding success, or productivity, is crucial for their long term conservation. It is a meticulous and vital task that involves carefully tracking the progress of a marked nesting site throughout the breeding season, from the moment the eggs are laid right through to when the young chicks fledge and head out to sea. The ultimate goal is to determine how many chicks successfully fledge. Many hours have been spent staring at the cliffs ledges so far and I'm absolutely loving every second of it, feeling the excitement every time you spot a new egg, then so eager to find the next!
My other research project is curlew, spending hours trying to track their movements, find territories and nesting sites. When you're looking for a brown wader in bracken this can get very tricky, but I'm loving the challenge! Hopefully soon we'll hear the pitter patter of little tiny curlew chicks running about!
