Brief description
This indicator is no longer maintained, and is considered OBSOLETE.INDICATOR DEFINITION
All known observations of seabird strikes are recorded upon observation at Australian Antarctic Stations and on ships travelling in the Southern Ocean.
TYPE OF INDICATOR
There are three types of indicators used in this report:
1.Describes the CONDITION of important elements of a system;
2.Show the extent of the major PRESSURES exerted on a system;
3.Determine RESPONSES to either condition or changes in the condition of a system.
This indicator is one of: PRESSURE
RATIONALE FOR INDICATOR SELECTION
Human presence in the Antarctic has led to the creation of many stations located around the continent. In many cases, these stations are sited close to seabird colonies. Birds have struck station buildings, radio masts, etc. Further, seabird strikes are reported from resupply and research vessels. In recent decades, there have been observations made of bird strikes, particularly colliding with station infrastructure, remote installations and supporting infrastructure and ship-based transport to the continent. Whilst the data are not considered to be comprehensive or highly rigorous, it is envisaged that recording of bird strikes may facilitate useful analysis in the future.
DESIGN AND STRATEGY FOR INDICATOR MONITORING PROGRAM
Spatial scale: Southern Ocean: 40S to the Antarctic continent, Mawson, Davis, Casey, Macquarie Island, Heard Island, field camps, and summer expeditions.
Frequency: Annual.
Measurement technique: Observation of bird strikes at Australian Antarctic Stations and at sea.
RESEARCH ISSUES
The accuracy of the data are likely to be limited as it depends upon the detection of bird strikes by actual observation of the strike as it occurs, or the discovery of bird carcasses near the structure with which it collided.

Statement: This indicator is now OBSOLETE. These data are no longer archived in this location, and are therefore not up-to-date.
The data are currently being compiled. The accuracy of the data are likely to be limited as it depends upon the detection of bird strikes by actual observation of the strike as it occurs, or the discovery of bird carcasses near the structure with which it collided.
