Pool party by Luke Massey, United Kingdom.
‘As the drought in Zambia’s South Luangwa national park stretched on, the waterholes dwindled to pools.
Flocks of Lilian’s lovebirds congregated together and when the coast was clear they descended to this pool.
They shuffled forward, taking it in turns to drink and bathe, as if on a conveyor belt.’
