Norway Rat Rattus norvegicus

Description

A rather cautious rat, that took a lot of enticing with tit-bits in the entrance way and on the trigger plate, and ended up getting caught just at the edge of the trigger plate.

Description

As the rat wasn't very interested in the trap yesterday, I added a bit of meat as bait. It certainly showed a lot of interest, but couldn't find the entrance! I suppose I need a little light over the entrance with a label in rattish.
It spent a whole second paused looking at the wall, not sure what the interest was.

Description

No mice, a howling gale, recycling blowing about ... and of course another rat. The reason for having the camera is to monitor the behaviour of animals around the trap, and here we see the rat pause before approaching the plastic container that is blowing about, then quickly sniff it on passing and then disappear. There is only a bit of cheese in the trap, not enough to entice the rat to investigate inside.

The still photos are from half an hour earlier when this rat is first seen near the trap.

Description

Another visitor, looks as big as the first, perhaps I haven't yet caught the smaller rat that was seen two days ago.

This one appears to have approached things with caution, and having entered the trap climbed through a small grill hole and came at the trigger plate from an odd angle.

Body about 19.5cm, tail about 17cm

Description

The larger of the two night time prowlers.

Body about 20cm, tail to base about 19cm.

In the infrared animation the rat enters the trap then there is an 8 second gap (that didn't get recorded) before the death rattle - probably eating bait in the entrance way and not moving enough to trigger the movement detection software.

I think. It was dead and boy I am certain it was not native.

Description

The same rat as yesterday turned up at 1:30am, 2:11am and 3:09am, but at 4:08am through to 4:20am a new rat turned up. Rather larger than the earlier one, I've uploaded a comparison photo and one trying to show the underside and tail length. It certainly has a light coloured belly, but the tail seems to be shorter than the body. Apart from the belly colour, I would think from the size that it is a Brown/Norway/Water Rat.

(Camera date stamp seems to be a day ahead)

edit: I've just noticed that my black trousers look white in infra-red, so best to ignore colour and/or shades.
