A good result for song meter sites sited within the NP (& beyond boundary of Pullen Pullen Reserve) under the auspices of Bush Heritage and Birds Qld as part of a broader Bird Surveying Expedition to the NP with Andrew Ley. 2- note call confirmed by N Leseberg, (Pullen Pullen Reserve) "one bird flew over that area on the night of 27 Sep, at about 10pm. You had a number of recorders there within a few hundred metres of each other, and the bird was detected on four of the recorders. Based on the times (see data below), it seems to have been moving west. Of the 8 calls detected, all are two-note whistle calls (I have attached a clip of the strongest call) and similar in structure, suggesting the same bird. There was one call of the 8 though that was higher and thinner. This may indicate a second bird, or it could just be the one bird doing something unusual.

So, while it’s not a roost site, it’s still valuable information. It is consistent with what we’ve found before, which seems to suggest birds roosting on the western edge of the escarpment country to the east of where this one was detected, then perhaps moving out onto the floodplains to the west to forage.

I’m sure your crew will be excited to hear the news. It’s not a roost site, and there is no risk of folks disturbing a sensitive area, so happy for you to share this data and the call clip around" 1/5/24
