This video says about itself:
In the southeast part of Norway you can observe the harvest mouse who is the smallest rodent in Europe.
In the Dutch coastal nature reserve Duinen van Oostvoorne, in the autumn of 2007 there were 100 live traps for small mammal research.
One brown rat was caught.
A bit unusually, bank voles were caught. Until two years ago, this species did not live on Voorne island. However, it is widespread there now.
Other species caught were: wood mouse 110 specimens; harvest mouse 31; common vole 13; Eurasian pygmy shrew 6; and common shrew 18.

Brown rat: a problem of identification?
March 26, 2008
From historical evidence, it seems that the Brown rat (Rattus norvegicus) arrived in Britain aboard ships from Russia c.1728-1729. However, the archaeological evidence is poor, primarily as a result of the difficulty in differentiating brown and black rat (Rattus rattus) on the basis of post-cranial bones. Most archaeological rat bones from the 16th century onwards are not identified to species, and the authors of this paper (Dobney and Harwood, 1999: 378) suspect that some earlier finds are identified as black rat on the assumption that the date is too early for brown rat.
Evidence for the absence of brown rat from early post-medieval Britain includes the apparent larger size of black rats in the past; some appear to be comparable in size to brown rats. This may reflect the lack of inter-species competition during these periods. Only three records of firmly identified brown rat exist in the North of England. The earliest comes from the Church Street sewer excavation in York (dated to between the 6th and 7th centuries AD). However, the find was recovered from the topmost, heavily disturbed layer and may therefore be intrusive. Medieval deposits at Jarrow also apparently contain brown rat, however the potential that this is also intrusive cannot be ruled out due to the little contextual information that exists. Finally, brown rat has been identified at Skeldergate, York, in deposits dated to the early 15th century AD, but the early date of this find is not discussed in the text and so it is difficult to establish the criteria for identification or whether there might be grounds for questioning its stratigraphic provenance.
