The sun is still shining (some of the time) and summer is still in the air but the wildlife will be starting to slow down a little. Our garden birds have successfully reared possibly up to three broods of young who have fledged the nest. Some species, such as Curlews, Starlings, Golden Plovers and Oyster Catchers are starting to flock together in quite large numbers now that breeding has finished. Take a look in the cut fields (favoured feeding area for many wading birds) in your area and you may spot Ruff and Black-tailed Godwit in amongst the flocks of Curlews. Our seabirds are also starting to head back out to sea for the winter so these first couple of weeks in August may be your last chance to head up to Sumburgh Head to catch a sight of the puffins.
Shetland has a variety of seashore habitats from the long pale sandy beaches of the South Mainland to the red sands of Eshaness in the North. An abundance of low rocky shore in between gives plenty of opportunities for a spot of rockpooling. One of the best spots is Leebitten at the North end of Sandwick which has a large expanse of seaweed cover rocks and pools at low tide.
Within these areas you will find an array of different species perfectly adapted for living in this harsh, ever changing environment. To find out more about the species to spot, take a look at our Inside a Shetland Rockpool post. And don’t forget to keep a look out for any alien invaders and non-native species, check out our Marine NNS post for more details.
It is a perfect summer activity to do with children giving them an opportunity to explore nature hands on, just remember to put anything you find back once you have finished looking at it and replace and upturned rock and weed.
If you plan on taking a trip to the coast, check the tide times first and be mindful of the rising tide. Do not go alone and always carry a mobile phone, f you find yourself in trouble call 999 and ask for the coastguard.
Moth of the Month- Large Yellow Underwing
The Large Yellow Underwing (Noctua pronuba) is a large moth with a wingspan of around 45-55mm. This distinctive moth gets its name from the yellow/orange coloured underwings only visible during flight when the forewings are open. It is a common resident moth in Shetland, active from July to September but often has a peak in numbers in August. Can be found in a range of habitats from moorland to grassland and gardens where, during the day they take cover amongst ground vegetation where they can be seen flying for cover if disturbed.
In other news…
Minke whales (Balaenoptera acutorostrata) are a relatively common sight around Shetland waters in August where they can be seen feeding just off the coast. They are the smallest of the baleen whales growing to around 8-9 metres long and living up to 50 years.
They are black to dark grey with a white underbelly and have distinctive white bands around their pectoral fins (flippers). They have a long, pointed snout and two blow holes on top of their heads.
Baleen whales- Filter feeding whales with large baleen plates in their mouths instead of teeth. Baleen is made from keratin, the same substance in hair and nails so is stiff yet elastic and is layered in plates in two rows along the top jaw of baleen whales somewhat like combs of thick hair. When feeding, water is taken into the mouth and pushed out through the baleen plates to filter out food such as krill and plankton which is then swallowed.
The most common UK sightings of Minke whales are in Scotland and Shetland has its fair share. They are often spotted from cliffs and headlands where they can be seen fishing in strong currents. They fish by taking in large quantities of seawater known as ‘lunge feeding’. Long pleats in their throat allow it to expand and take in large mouthfuls. The water is then forced back out through the baleen plates and the prey swallowed. They have a varied diet feeding on a range of small fish, krill and zooplankton.
“The minke whale, like all cetaceans, is protected as a European Protected Species (EPS). EPS legislation protects all species of cetacean from deliberate and reckless killing, injury and disturbance. Information on how to minimise the risk of activities which may kill, injure or disturb minke whales is set out in Marine Scotland’s guidance on The protection of marine European Protected Species from injury and disturbance.
The minke whale is also a Priority Marine Feature in Scotland’s seas and has recently been included within two of four additional Nature Conservation MPA proposals for designation to complete the Scottish MPA network.
The Scottish Marine Wildlife Watching Code provides the best guidance for wildlife watching operators, and will help us all enjoy and support the conservation of this wonderful baleen whale.”
