Bird Sightings

By Greg Lee

A calm start to the day with fog and light rain curtailing any opportunity to open the nets in Millcombe. With a busy day for the boat, my main task was joining Emma out at Jenny's Cove to run the seabird station mid-afternoon after tackling some of the rarity descriptions for the spring early morning. 

On my journey out to Jenny's Cove, I sighted a Meadow Brown whizzing over the ground, my first of the year for this grassland butterfly species of high summer. Certainly it made me think of the numbers that would be out across some of my favourite Cotswolds butterfly haunts, Prestbury Hill, Rough Bank, Swift's Hill, Daneway Banks etc. In the long grass, a Heath Spotted Orchid was still in flower, though was surprisingly cryptic. I also spotted a Swift scything through the air, just one of many seen by several observers across the island today. At this time of year, many non-breeding adults will wander around looking for potential nest-sites for the following season. These immature birds are sometimes known as "bangers" as they will knock potential nest-sites to check if they are occupied. In Jenny's Cove itself, the gurgling of Guillemots and whinnying of Kittiwakes filled the air and it was certainly a good show of Puffins, all in all making for a good day for showing members of the public our special seabird colonies. A Kestrel passing through interesting sighting, we're speculating that at least three individuals are currently on the island at the moment.

Later on, we said goodbye to researcher Jayden Parker who has been with us for the past three weeks. As we headed down to say our goodbyes at the Oldenburg, we noted an impressive amount of jellyfish in the Landing Bay, mostly Moon and Blue. A small shoal of Sand Eels shimmered as they caught the light, these fish are a very key part of the diet of many of our breeding seabirds. Fortunately, the waters were quite settled and with the low cloud, made for quite a pleasant late afternoon.

Other sightings across the island for the day included a Reed Warbler chuntering down in Millcombe, two House Martins moving south and a grand total of 26 Swifts passing through. 56 Painted Ladies reflected the further increase of these butterflies.

This morning I headed through the low hanging fog to Aztec Bay for my Guillemot and Kittiwake monitoring, a very atmospheric walk with grazing Soay Sheep appearing from the haze. I stopped to appreciate some English Stonecrop flowering on Halfway Wall, its flowers like star bursts among the Lichen.

Thankfully the fog sat like a hat on the island and as I ventured down to my monitoring plot, the colony emerged clear as ever. Today was an exciting day for me as Greg has been carrying out the Guillemot and Kittiwake plots while I focused on Puffins, which means while I've been seeing lots of Sandeel visits, he got to see the first chicks yesterday. I had certaintly been missing out. The Guillemot chicks were only a few days old with spiky looking down and still showing their egg tooth, a hard addition to their beaks to help chicks break out through the thick egg shell that is indicative of a new hatchling. I managed to spot 41 in my little plot with many other birds still incubating eggs and likely sitting on hidden chicks. Kittiwakes were more secretive with their chicks today, parents keeping them warm underneath their bodies in their nests, but observing them shuffle and change position I managed to catch a glimpse of various downy balls of fluff.

After nests were checked and chicks were admired I headed to Jenny's Cove for the Seabird Station. It was a busy day with both a large ambassador tour and a school group passing through to peek at the puffins. It was lovely to chat to over 70 visitors about our seabirds and everyone got to see through the scope with the fog descending just as the last visitors turned heel for the village.

Elsewhere on the island it was another quiet day for new birds with the evening wildlife log in the tavern consisting of the common breeders and their fledgelings, especially as most of the rest of the team had been on Housekeeping and were too preoccupied with linens and polish to look out for rarities passing through.

Happy Monday, I hope you all had great weekends!

Yesterday morning, Thomas, Lucile, Jayden, Tara and I went out to catch 3 Mallard ducklings to ring. This went very smoothly and was exciting as not many Mallard get ringed on Lundy. We hope to go back next week to ring the adults while they moult. 

This morning started with a seal disturbance survey at Brazen Ward. It was fairly high tide so there weren’t many seals about, most were probably off foraging. However I was treated to the cool sight of a Peregrine flying right past me, carrying a freshly killed bird (unfortunately it passed too quickly for me to tell the species)!

Next it was off to the Landing Bay for the first snorkel safari of the year! Despite the visibility being less than ideal due to some easterly’s we still had a great time! After getting fully geared up in neoprene we found lots of awesome marine life! Some of the highlights were Cowries, some big Shrimp, an intact Edible Crab moult, Dead Man’s Fingers coral and Jessie found a Nudibranch!

It was a bit of a slow start for the conservation volunteers this morning, as island karaoke went on until very late last night. After 3 strong cups of coffee, I began to walk up to the northeast of the island to complete my scheduled seal disturbance survey. I was rewarded for my efforts by many butterflies along the way! This was one of the first sunny days since I have been on the island, and it was lovely to see the migrant butterflies and moths in full force! We had a total count of 40 Painted Ladies across the island, and around 30 Red Admirals. This is a big step up from last week, when I walked the butterfly survey route and only saw one Small Tortoiseshell.

Unfortunately, I did not see as many Seals during my survey.  I also witnessed quite a bit of disturbance of resting seals in the bay, with several seals scared off the rocks into the water by a boat.  There were only four seals in the bay when I got there, which is crazy as last week at the same site, around the same tide, there were 38 seals. For most of the survey, I watched one lonely seal (she was pretty cute though!). The decrease in numbers at this site is likely due to disturbance.

Grey Seals “haul out” (flop onto the rocks) during the hours around low tide to digest the food they caught while the tide was higher.  If the seals get stressed during this time, they cannot digest their food properly, so they lose a lot of energy.  Even something as small as people walking on the cliff nearby can cause enough stress to disrupt digestion in a seal. Regular disturbances like this have been shown to have some very severe impacts on seal colonies over time, like causing them to move to areas that do not have optimal conditions for them or shortening their lifespan. The Seal Research Trust has some great resources about this on their website:  What to do if you see a disturbed seal.

When Chloë and I do our disturbance surveys, we are watching the seals for any signs that they are stressed. We note down the causes and how severe their stress is based on how they act. A seal that is looking around at you or at something else while hauled out, has been disturbed slightly. A seal shifting or moving positions on the rock while looking around has been disturbed more, and a seal that rushes off the rocks into the water, or dives down with a splash, has been severely disturbed.  We do these surveys to measure how much disturbance effects our seal colony, so that the island's warden team know when and how to act to mitigate any disturbance that could have long-lasting impacts. The island's seal colony is impacted by disturbance a lot, especially since they are known to be very friendly, so they attract many visitors. If you witness any severe disturbance incidents whilst on the island, please do report these to the conservation team, with evidence if you can!

After my survey, I took my time to the walk back, as I wanted to count all the butterflies I saw outside the census route on the way. I also kept up a count of the bird species I saw. I am not as good at counting as some of the other volunteers, but hopefully I will get better over time! I counted 13 Painted Ladies, 8 Red Admirals, 7 Small Heaths, 3 Shags, 7 Oystercatchers, 9 Linnet, 5 Skylarks and two Carrion Crows on that walk. I also met a friendly Rose Chafer beetle! I took a lot of photos along the walk as well. I returned from my travels to make some tasty pasta, then spent the rest of the day trying to get the seal disturbance videos I had taken onto my laptop and hanging out with the other volunteers. An early night was required, and I fell asleep as soon as my head touched my pillow!
