G'day B-aus Members
A number of people have let me know that they never saw any White-
throated Needletails during the last "Swift Season"
IF you normally do, BUT did not see any in this last season (or any
previous season that you can recall) Would you mind letting me know
[preferable off-list] as I am establishing a record of zero sightings
to compare with the actual sightings I have been recording for 40
years. I think this will have value as I believe many WTNT spend
most of their "Winter in Aussie" in a reasonably confined area. When
the weather conditions are right they may leave these areas to
temporarily visit less favourable areas. I think this explains why
WTNT are almost always seen in some areas, but in others are only
seen when the weather conditions favour their finding food in these
areas, and will also assist in providing cheap transport to those areas.
Happy birding
Mike
