Hello all,  

Whilst on a birding trip on Cape York Peninsula {October 98} a friend
videotaped an incident which showed his discovery of a small hole {abt 3 or
4cms wide)in a tree trunk from which a threatening growl would come if the
trunk was scratched or the hole entrance touched with a small stick
He found two of these holes from which this loud growl could be provoked,
the first about 2m up the trunk of a small tree , the second nearby in a
different tree about !/2m above ground level. The ominous and quite loud
growls could be stimulated by movement close to the site of the hole in
each case.
The sound emitted is rather intimidating and normally would be expected
from a creature too large for such small apertures..
The actual site of is within rain forest on the Claudie River in Iron Range

Can anyone throw any light on the possible source of these strange sounds ?
Not a birding question but one of those intriguing consequences of our

Ps.His travelling companion did not respond well to a request to "put your
finger in ."
