With covid situation hampering our seabird ringing research program this year we decided to combine two trips into one. As none of the pre-booked UK bird ringers were able to travel, Channel Islands Ringing Scheme members stepped in travelling from Guernsey by boat directly to Burhou to get the job done. The task ahead was to focus on the Storm Petrel colony over two nights and by daytime colour ringing the Lesser black backed Gull colony, plus ringing any other species chanced upon. Burhou is less than a mile from the NW corner of our island and just a 10 minute boat ride from Alderney. Soon after landing our team set up nets for at the NE end of the island ahead of the first Petrel ringing session. During the short walk from our Burhou hut base/accommodation we saw a resident Peregrine Falcon and then a migrating Honey Buzzard that headed towards mainland Alderney. Opening the nets as the light fell away our first bird to ring was a Rock Pipit. This species does exceptionally well on Burhou with several nesting pairs resulting in 50+ Rock Pipits occupying this tiny island. Further investigation of Rock Pipits here may prove very useful given there is nationally very little base-line data pertaining to this species. Soon we were fully employed as a steady stream of Storm Petrels, a truly delightful nocturnal seabird, visited our two 18 meter nets. Petrels tend to come in waves and our keen ringers worked exceptionally well as a team regularly changing roles to strengthen either the ringing or extraction team where they were most needed and best deployed. We worked non-stop through the night until 4am when we closed the nets ahead of first light. The following day was extremely hot so we delayed ringing any Gull chicks until the late afternoon to ensure none were exposed to the sun. It soon became very clear that these Gulls have had a very good breeding season as we ringed almost 50 directly behind the Burhou hut, a significant increase on chicks in this same area in recent years. Luckily the winds remained low with no rain forecast so our second night of Petrel ringing, now on the NW coast, could go ahead. As with the previous night we deployed two 18m nets (no tape lure). The night flew by with our team once again operating like a well oiled machine as the numbers of Petrels ebbed and flowed. As it turned out some 605 Petrels were processed, weather conditions were similar both nights as were the results with just under 300 birds processed the first night and just over 300 the 2nd. 514 new birds were ringed, 86 were re-traps and 5 foreign controls (4 UK & 1 French). Just under 50 Lesser black backed Gulls were colour ringed along with 2 Herring Gulls. We also chanced upon and ringed 2 Shag chicks and a single Rock Pipit. Amongst the re-trap Petrels 3 were 15yrs of age and one individual was 17yrs old. Passing migrants included Grey Heron & Common Sandpiper. Given the obvious difficulties this year the ABO is delighted to have undertaken a significant proportion of the seabird research. The boat work was excellent landing our team safely, indeed the whole trip passed without incident. Thank you again to the local ringers for stepping in and doing a grand job. Storm Petrels have been ringed on Burhou since 1946 and the ABO is very proud to be leading this area of research now and into the future.
