A Surprising Find at Bell Lane LNR.

Whilst surveying the Bell Lane Local Nature Reserve in Staplehurst this spring I was pleased to find small numbers of palmate newt in an area which is dominated by smooth and great crested newts.  A greater surprise, however, was what appeared to be a smooth x palmate newt hybrid in one of my bottle traps.  This animal, a male, had a filament on the tail, a low crest and the rather square cross-sectional shape of a palmate newt.  The tail was broadly similar in colouration to a male palmate, although it had an orange margin along the underside.  The upper body colour was more typical of a male smooth newt, Smooth_x_palmate_Bell_Lane_LNRhowever, as was the throat and belly which were marked with large blotches, although these looked more washed-out compared to a normal male smooth newt.  The hind feet resembled neither species.  There were no toe fringes, and only slightly developed rather translucent webbing, with a strong pink colouration to the limbs.  The specimen was larger than the other palmate newts found in the pond.
Interestingly when viewed at night by torchlight the animal tended to look more like a palmate, whilst in daytime it was more reminiscent of a smooth newt, something I noticed in a similar likely hybrid I found in East Sussex last year.
