Caldene Fields, Raw Nook Nature Reserve and Toad Holes Beck are located at Low Moor in South Bradford. Caldene Fields is eight acres in size and is adjacent to Raw Nook. The flora of the site is predominately old meadow with a scattered of Hawthorn bushes.
There is a pond located to the south east of the site, which flows directly into Raw Nook and through into Toad Holes Beck. The view of the fields is from the Watch Point with Emley Moor mast on the horizon to the S/E. The fields are private but can be viewed from a public footpath.
Given the fields are set in an urban location, Visible Migration is quite good particularly in mid October but at times can be very hard work. Over the years grounded birds found using the urban migration route have included Pied Flycatcher, Ring Ouzel, Cuckoo, Black Redstart, and at least seven species of wader. The area supports breeding Lesser Whitethroat.
Anyone wishing to visit this urban site should be aware an early visit is advised to avoid disturbance from dog walkers and the general public.
