Hartlaub's Gull

Hartlaub's Gull Hartlaub's Gull

 

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 centres, rubbish dumps, cultivated farmland and estuaries.


Search human inhabitations 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.
Control:

    This design is spectacular! You most certainly know how to keep a reader amused. Between your wit and your videos, I was almost moved to start my own blog (well, almost...HaHa!) Great job. I really loved what you had to say, and more than that, how you presented it. Too cool!
