Beach Patrol

Walk along any beach in Africa and – sooner or later – you’ll see a small, pale plover hurrying away from you. Typically, there will be a pair of these active little birds and at no time will they take their beady, deep-brown eyes off of you.

The White-fronted Plover feeds on small invertebrates such as isopods and larval crabs which are chased and then snatched up with the sharp bill. Like many coast-living birds, these plovers occupy and defend linear territories the size (length) of which is dependent upon the density of prey. On a recent short visit to Benguerra Island in Mozambique, I counted four pairs over a three kilometre stretch which gave an average territory size of 750 metres. When they move up and down their stretch of the shore, these chubby little plovers are not only in pursuit of  food, they are on active beach patrol, keeping others of their kind away.

Two or three superbly camouflaged eggs are laid in a shallow scrape in the sand on the upper beach, often among shell shards or the trailing stems of the Beach Morning-Glory (Ipomea pes-caprae). And should a potential predator threaten the clutch, one or both parents will perform a distraction display – which may involve feigning injury – to lure the danger towards them and away from the eggs or young.
