A recent stranding gained media attention last week as a Risso’s dolphin (Grampus griseus) washed up on a beach in Norfolk. The Cetacean Strandings Investigation Programme (CSIP) receives around 10 reports of Risso’s dolphins stranding every year, but most of these reports are concentrated in Scotland and the west coast of the UK. This unusual stranding in the southern North Sea meant it was crucial for the CSIP team to retrieve this animal for post-mortem. Post-mortems are essential for us to understand how the animal died, and the possible series of events which may have contributed or occurred leading up to its death.

April 14 2018 is Citizen Science Day, the start of a week celebrating all the amazing ways that people around the world contribute to science.
Citizen scientists are people like you and me, everyone from school children, to families, to dedicated volunteers, to local nature groups. Some go out into the wild to find and record nature, but you can even do science by joining projects at home.
Whilst Joe Beale and Wildlife Garden bird recorder Florin Feneru were focussing on birds, as reported in our previous blog, it was also a good time to take stock of other species we’ve seen. They may not be visible during the early part of the year, but were very much in evidence in the warmer months of 2017 and hopefully will soon reappear – in between the heavy rain showers and cold spells…
When a call comes in to the Cetacean Strandings Investigation Programme (CSIP) hotline, the details of a stranding can often be minimal and somewhat vague. An animal may be highly decomposed, inaccessible or lack features for it to be identified. As a research assistant for CSIP, my job is to investigate a stranding and try to gather as much information as possible so an accurate identification can be made. This blog post provides a simple guide for everyone to try and identify dolphins, whales and porpoises commonly washed up on British coastlines.

As we work through the Wildlife Garden on seasonal tasks – completing the clearance and shredding the huge numbers of London plane tree leaves, coppicing and hedge-laying – there are always plenty of wildlife distractions to remind us of the value of this urban oasis. Wildlife gardener/Ecologist Joe Beale describes recent avian activity in the garden:
‘As the autumn progressed, flying insects and flowers naturally become harder to find and birds replaced them as the most noticeable feature of the Wildlife Garden.
At this time of year we start to prepare for our annual pond-clearing tasks which include pulling out some of the reeds along the pond margins and thinning water-lilies – all to maintain our open water pond habitats.
In the meantime, volunteers Miles Äijälä, Rohit Bangay and Frances Dismore give an account of a very different pond activity in April this year:

Our latest blog by Alex Mills from the current cohort of trainees takes a look back a few weeks to the BioBlitz in Tring, Hertfordshire:
‘What is it? What’s on me?’
‘Wow. It’s huge, Mum!’
‘Ah, cool. Hold still…’
Unconventional collection methods can work wonders during a BioBlitz. In this instance a mother accompanying her children on a minibeast hunt found herself functioning as a perfect interception trap for Stenocorus meridianus, a rather imposing longhorn beetle. The beetle was duly potted and admired. Everyone (including the mother/beetle trap…eventually) was transfixed by this magnificent beetle. And that was the order of the day at the highly successful Tring BioBlitz a few weeks ago: enjoyment and biological records, with kids and adults of all ages being transported by the natural world around them.
The warm, sunny days that alternate with the frequent, damp weather days this month release a burst of colourful insect activity for visitors to observe amongst the variety of habitats and flowering plants in the Museum’s garden. Joe Beale, who has recently joined the team, tells us more.
Late summer is a lively time in the Museum’s Wildlife Garden. On sunny days you may catch sight of some of our most impressive and colourful insects. Dragonflies that use the garden include the stunning green-striped southern hawker (Aeshna cyanaea), the impressive migrant hawker (Aeshna mixta) and the imperious Emperor dragonfly (Anax imperator).
They may buzz you to investigate, but tend to power up and down without stopping like little fighter planes, as they hunt flying insects around the meadow, hedgerows and ponds.
