Pigeon poo is threatening the Alexandra bridge across the Clutha River, so the birds have to go.

New Zealand Transport Agency (NZTA) senior asset manager John Jarvis said the bridge’s structural steel was being corroded and, while it was not an immediate safety risk, action was needed to reduce the 400-strong flock of resident pigeons so damaged areas could be repaired.

The corrosion mostly affected the surface, but there were also some cases of pitting. (more…)

7 Ways Pest Birds Cause Damage

Monday, August 9th, 2010
The acid in bird droppings will eat into many tar-based roofing substrates. Without effective bird deterrent measures, these droppings will accumulate , allowing the acids to eventually perforate a roof and leave it vulnerable to leaks. Bird nest built under clay roofing tiles can also cause leaks when tiles are displaced.
Roof nests and nesting materials, especially those of pigeons, starlings and sparrows, are notorious for clogging rain gutters, drains and roof corners. Many industrial buildings with flat roofs suffer water build up and collapse during rains due to clogged  gutters and spouts. Proper bird control can keep birds out of gutters.
Nesting materials and acidic bird droppings can severely damage A.C. systems, vents and compressors. Rotating air circulation vents, skylights, and solar panels—all can be damaged to the point of inoperability. Bird droppings can block exterior security cameras and “freeze up” their motion servos. Bird deterrent measures help prevent this damage
If you’re looking to start a fire and need some good kindling , bird nests are ideal. The straw, twigs and dried droppings ignite at the slighted spark. Which is why bird nests inside electric signs or other machinery pose such an extreme fire hazard.
Bird nests built in chimneys and ventilation systems can create potentially lethal air blockages . Bird control is a must in these situations.
The acids in pigeon and gull droppings can eat into painted finishes on cars, BBQs, boats and anything else left unprotected. Unless removed, these acids will eat deeper and deeper, permanently destroying the painted finish.
Birds who invade warehouses, loading docks and storage areas can chew into packaged food products and contaminate them. Bird control can save retailers millions of dollars in waste.
