Nosy neighbour by Sam Hobson, UK. Sam knew exactly who to expect when he set his camera on the wall one summer’s evening in a suburban street in Bristol, the UK’s famous fox city. He wanted to capture the inquisitive nature of the urban red fox in a way that would pique the curiosity of its human neighbours about the wildlife around them.

Behaviour: Mammals category. Giant Gathering by Tony Wu, USA. Dozens of sperm whales mingled noisily off Sri Lanka’s northeast coast, stacked as far down as Tony could see. This was a congregation of dozens of social units, like a gathering of the clans. Aggregations like this could be a critical part of the whales’ rich social lives but are rarely reported. Some two thirds of the population was wiped out before commercial whaling was banned in 1986. This kind of major gathering could be “a sign that populations are recovering”, says Tony.
