Hartlaub's Gull - Larus hartlaubii

Summary:

The Hartlaub’s Gull is an indigenous tame sea bird, increasing in numbers.

They often hang around gardens, parks, and restaurants, follow fishing vessels looking for scraps or follow ploughs looking for soil invertebrates.

Those in urban areas will catch insects at street lights at night.

Roost on roofs, hedges, or islands.

 

Habitat:

Seashores, offshore islands, city centers, rubbish dumps, cultivated farmland, and estuaries.

Scavenge human habitations like parks and restaurants for scraps of food.

 

Breeding:

Roosts on rooftops, ledges, and islands;

Nest made of twigs and shells;

Cultch: 1-3 (in some cases up to 5-8).

 

Damage:

Uric acids in feces are highly corrosive: Feces cause damage to waterproofing of roofs causing leaks; feces damage paint work of automobiles with regular/long contact; feces also damage air conditioning units and solar panels;

Degrading the aesthetics of potentially neat and beautiful buildings;

May cause a health risk when HACP standards are not met by food processing companies as a result of birds entering factories and warehouses: bird droppings damage and infest raw materials, products in-process, and finished goods;

Nests near electrical points/lines or in chimneys are a great fire hazard;

Bacteria, fungal agents, and ectoparasites in droppings may be a health risk;

When they move in flocks the buildup of their feces has a great impact on buildings;

Often dive down, grabbing fisherman’s fish or scraps of food from people.
