Unlucky Grey Heron (Ardea cinerea) failing to catch two Brown Trout (Salmo trutta) at Annacotty Weir on the River Mulkear, Co. Limerick, earlier this week.

Very nice footage of Otters (Lutra lutra) on the River Mulkear downstream of Annacotty weir, Co. Limerick, November 2025.

Otters (Lutra lutra) at Annacotty Weir on the River Mulkear, Co. Limerick, last week. This is a mother and a juvenile.

Juvenile Otter (Lutra lutra) at Annacotty Weir on the River Mulkear, Co. Limerick, last week. Watch until the end of the video when its mother makes an appearance.

Selected autumn trail-camera footage from a site in north Co. Tipperary, featuring a Badger (Meles meles), Fallow Deer (Dama dama), and a Fox (Vulpes vulpes).

This was captured using a 'white-flash' camera, which uses an LED light to illuminate the scenes.

Golden Plover (Pluvialis apricaria) on the Shannon Estuary last week. Most of the Golden Plover seen in Ireland are winter visitors from Iceland.

Current trail camera footage wild Red Deer (Cervus elaphus) at a site in east Co. Clare. Unlike the Killarney herd, these deer are descendants of more recent introductions and are not considered native.
