As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Taking Birds Off The Map


November 3, 2012
The U.S. Pacific Air Forces issued the following news release:

For almost one year now, Airmen 1st Class Marnell Dillingham and Jarrett Dowey have been cruising around the flightline three times a day, armed with a pail of bird scare ammunition and two shotguns. While out there, their role is to scare birds that fly too close to the flightline.

The two 35th Operations Support Squadron Airmen help reduce bird strikes on the flightline. According to Birdstrike Committee USA, these environmental hazards have been the cause of hundreds of deaths and millions of dollars in aircraft damages a year.

"Preventing bird strikes is one of the most important parts of our job," said Dillingham. "If a bird strike happens, it could put our pilots, crew members and passengers in a very dangerous situation. Birds have been known to cause aircraft crashes."

The Federal Aviation Administration receives annual reports recording thousands of wildlife related strikes. Strikes involving military aircraft cause approximately $75 million in damage a year.

In an effort to combat this environmental hazard, the Department of Defense pushes to improve aviation safety programs. One of these programs, the Bird and Wildlife Aircraft Strike Hazard prevention program, requires constant interaction among aviation safety members, air operation shops, pilots and aircrews.

"To ensure the safety of everyone, we coordinate constantly with the aircraft safety office, the supervisor of flying operations and the airfield control tower," said Dillingham.

There are two types of control measures, active control and passive control, said Dowey.

Active control is when pyrotechnic, bioacoustics and depredation methods are used to provide short-term relief. Pyrotechnics use BASH cannons, which produce loud, booming sounds to scare off birds in the flightline area. Bioacoustics, or the broadcast of local bird distress signals, is another way to provide immediate, although short-term, relief. Depredation allows Airmen to scare off birds that roost on the taxi-ways and cannons by shooting at them with shotguns loaded with bird scare cartridges.

Passive control measures involve environmental factors, such as maintaining grass height, smoothing out hills and eliminating forestry. Trees, shrubs and other plants can draw in wildlife for food, shelter and roosting sites for birds, so it's important to eliminate them from aircraft flying area. By smoothing out hills, it maintains the draining of streams in wet areas.
