Cumbria Biodiversity Data Centre

The Cumbria Biodiversity Data Centre at Tullie House Museum, Carlisle keeps wildlife information for the county of Cumbria. Tullie House Museum, in its role as a local natural history museum, has collected and disseminated records of wildlife in Cumbria since its inception in 1893. From the early 1990s the Museum has developed a computerised database of species and habitat records in Cumbria and has taken the central role in providing a local biodiversity data service for the county. This role was restyled as Cumbria Biodiversity Data Centre (CBDC) in 2010, a not-for-profit organisation hosted by Tullie House Museum and advised by local stakeholders.

NOTICE- NBN Bird Records: NBN are updating BTO's Birds dataset on the NBN Atlas this week. To do so they will have to delete all 151 million records and upload the new dataset. This will take about 3 days to complete. There is more information on the update here: … bn-atlas/.

Planning your space for Pollinators. Free webinar tomorrow (18th) 1pm-2pm. Whatever size your site is there will always be space for plants which are nectar rich for pollinators. This webinar will identify which plants are they and where should they go: shade, sunny spots, damp ground and hedges etc. Book

Field voles (Microtus agrestis) and bank voles (Myodes glareolus)

Between April and September every year the CBDC receives a large number of records for field and bank voles. There are currently around 600 records per species many for multiple individuals, with the earliest bank vole record dating back to 1887! These species have very similar appearances and it can be difficult to tell them apart, but there are a few tricks to identifying them with the voles having morphological and behavioural differences that can be spotted.

Bank voles are often more visible and active, commonly seen climbing, with a preferred diet of blackberries and hazelnuts. They can be found in variety of habitats such as woodlands, hedgerows and gardens, they are widespread in the UK though absent from many smaller islands. They can be distinguished from field voles by the size of their tail which is 50% of their body size, as well as, their larger eyes and redder fur colouration.

Field voles are difficult to spot as they stay close to the ground moving quickly through small paths, they are found mainly in grassland, heath and moorland. They are found throughout the UK and are one of the most common mammals in the UK. In terms of their difference in appearance to bank voles field voles have a greyer coloration and smaller eyes with their tail only 30% if their body size.

Both of these species are an important prey item for a number of owl species with field voles alone making up 45% of a barn owls diet! They are also great feed for barn owl young. Dissecting owl pellets can be a great way to identify small mammal species in your area, through skull identification, field and bank voles can be distinguished by their teeth.

For more information on barn owl pellet dissection and identifying mammals follow this link;

Below a comparison of field and bank voles, as well as a photo of some barn owl chicks from a recent record.

Swifts- Apus apus!

Last week was Swift awareness week and it reminded us of Bryan Yorke's talk at the 2016 Recorders conference.

Bryan spoke about Swifts in the Community, a conservation project active in South Cumbria and North Lancashire, recording Swifts and their nesting locations. He described a fantastic way to help Swifts in your local area. For more information follow this link to their website:

Swifts depend on humans for suitable nesting sites that they loyally return to each year, however buildings have changed and are often not suitable for swifts to nest, leading to a 40% decline in the UK swift population in the last 20 years.

• Swifts are the fastest flying bird at level flight at around 60mph, covering around 500 miles a day.
• Swifts only stop flight to nest, normally they would even sleep in flight drifting safely at around 10,00 feet.
• Young Swifts can enter semi-hibernation due to the sporadic feeding they receive, while their parents catch hundred of insects in a large ball that they carry with them in their mouth.

French photographer Jean- Francois Cornuet uses slow motion film to study how swifts, preen, scratch and live their lives on the wing.

Young mudshrimps Corophium are growing & moulting right now; a friend once described the piles of cast exoskeletons as 'like snow-drifts' along the shore. Not quite such dramatic nos. here but I was thrilled to find them - the long antennae are clearly seen CumbriaBDC photo
