We take a diversion this week from the Microverse and our newest project, Orchid Observers, to introduce one of the projects that wouldn’t get anywhere without the general public reporting sightings, the UK Cetacean Strandings Investigation Programme (CSIP). Cetaceans are the infraorder of marine mammals that includes whales, dolphins and porpoises, and the Museum has been involved in recording their strandings on UK shores for over a century. So it’s over to Rebecca Lyal, Cetacean Strandings Support Officer at the Museum, to introduce the project and what she does as a part of it.
Warning: You may find some of the images that follow upsetting as they are of stranded and injured animals.
The CSIP was created in 1990 to unite the Museum with a consortium of interested parties to formally investigate the stranding of any cetacean, seal, shark and turtle upon the UK coastline. The Museum has actually been recording strandings since 1913 when the Crown granted it scientific research rights for the collection of data on the ‘fishes royal’.
The first recording was a Cuvier’s beaked whale that stranded in Northern Ireland during the summer of 1913. Since then there have been over 12,000 logged reports of whale, dolphin and porpoise strandings, that have ranged from the mighty blue whale to the common harbour porpoise, and even a rogue beluga whale found in Scotland.
The rich warbling song of the blackcap has welcomed us into work over the past 2 weeks! (you can hear an Eurasian blackcap, Sylvia atricapilla, as recorded by Patrick Aberg here). Not only that but we’ve had robins nesting just above the threshold of our shed with the accompanying chatter of baby birds anticipating food, holly blue butterflies visiting clusters of fresh holly flowers, sightings of orange tip, brimstone, peacock and speckled wood butterflies, tadpoles in the main pond, the occasional glimpse of a fox cub, and many more signs that Spring has well and truly sprung.
The mosaic of ground flora throughout the different habitats in the Garden is changing by the day with a particular blue haze and glorious scent of bluebells in the woodland areas.
While winter tasks in the Wildlife Garden kept most of us busy outside for the first quarter of the year, these cold months are also a good excuse to hunker down inside and look back at the previous season’s species records, enter new records on our database and consolidate reports on our findings.
As mentioned in one of our early blogs biological recording is carried out – like most activities here – with the help of many volunteers (specialists as well as beginners), and naturally our own scientists, during the course of their working day. Sometimes we enlist the help of aspiring young scientists…
Recording is carried out by observation and surveys. From mosses on walls, rocks and bare ground and the animals that inhabit these miniature forests, to the tree tops where great and blue tits may be spotted feeding on aphids and other small insects in the upper branches, as well as high flying butterflies such as the purple hairstreak that feed off honeydew.
Invertebrate surveys are carried out using a variety of methods including pitfall traps for ground invertebrates, malaise traps for flying insects, and light traps for nocturnal fliers.
