Bird call

Kowhai tree in bloom

Does anyone out there know anything about bird calls and indentifying birds.

For about 2 weeks we have had this bird around our place making a call we think to try and attract a partner to no avail.The call is somewhat tui like but definetely not what you normally hear from a tui. The bird itself looks like a tui from a distance - not having been able to get close and it sits in all the known tui habitats - norfolk pines, banksias etc.

The bird call itself is quite long with 6 or 7 notes and it is almost as if the bird has lost its mate and is deperately looking for it - my interpretation here.

Any help or ideas would be appreciated.
