Hi all
While counting up my Australian bird list recently some questions were
raised by a non birding friend re geographical limits that apply to
record species on the Australian national list. I showed some recent
posts about Christmas Island birds titled "New Species for Australia"
indicating that this is what we do and generally the list is developed
around political boundaries relating to the nation and its territories.
However I was unable to give easy answers to the questions.
For example, if the reason is political boundaries, why are not all New
Guinea birds recorded on the Ausie historical list? Are birds
recorded from French Polynesia in the Pacific or Reunion Island in the
Indian Ocean considered part of the French national bird list? Are
birds recorded from Diego Garcia in the Indian Ocean part of the UK bird
list? Outside of Australia do others follow the same rules? If so
is there any part of the world that would not qualify for the US list?
The exercise has left me wondering about the rationale of recording
national bird lists.
During the exercise some interesting geographic facts about Australia
and its territories were indicated.
The closest Australian mainland location to Christmas Island (South
Point) is North West Cape (Jabiru Point), distance 830 Nm. (1538 km.)
However the distance from Christmas Island to Java, Indonesia is only185
Nm. Cocos Island to Australia (Jabiru Point) is 1137 Nm (approx. 2100 km).
Hoping we can have a friendly discussion about this subject.
