Hi Mike,



I recorded WTNTs flying over the north-western slope of Transit Hill on Lord
Howe Island during two recent bird flight path survey periods (21-25
February 2016 and 14-18 March 2016).



1st Observation:



25 February 2016, 0545 - 0610 h: 18 individuals travelling in a northerly
direction in front of a weak storm front (no rain).  Flying low & circling
over the slope, ranging 10 - 30 m in altitude (m above ground level), as
they slowly moved northwards.



2nd Observation:



16 March 2016, 1510 - 1525 h:  at least 8 individuals travelling in
north-easterly direction in front of storm front.  Flying low & circling
over the slope, ranging 2 - 20 m in altitude, as they slowly moved
north-east.  Heavy rain followed soon after, lasting c. 30 min (1530 - 1600
h).



3rd Observation:



17 March 2016, 1620 - 1715 h: at least 12 individuals travelling in
south-westerly direction in front of weak storm front (no rain).  Flying low
& circling over the slope, ranging 1 - 30 m in altitude, as they slowly
moved south-west.



Co-ordinates for all three observations:   Latitude: 31 deg 31.8 sec South;
Longitude: 159 deg 4.5 sec East.



Kind regards,

Stephen
