Britain's smallest deer might be spreading all over the country, but can they really be seen and heard in some of our biggest cities, next to motorways and in parks during the autumn? Simon King's going to find out.

It's difficult not to fall for this charming little red-brown deer. Spotting one can be difficult as they are secretive and wary, and unlike our other deer which herd the muntjac is a solitary animal. Persevere though and you'll be rewarded with one of the most charming looking wild animals in the UK. The antlers are small and straight (up to 10cm long) and form a v-shaped ridge on its face. Its protruding canine teeth look a little like tusks. Also, note the rounded and arched back.
The muntjac might only be about the size of an average dog but its hardiness has seen it adapt superbly to life in this country. Originally introduced to Woburn Park and Whipsnade Zoo from south-east Asia, over time some were released or escaped into our countryside. Since then, as it can breed all year round (our other deer mate only during a seasonal rut), it has spread all over the country.
Listen out for its repeated loud and sharp barking or yapping, which is used as an alarm call, to announce its presence and challenge other males. This has led to some people calling it the barking deer.
Habitat-wise, it likes to live in thickets and bushes in woodlands and places with plenty of cover and dense vegetation, including over-grown gardens.
Muntjacs cause less economic damage than our other deer, but can cause problems where the numbers are high. Being hit by cars is a problem, so drive carefully!
