Five minute bird call survey
The five-minute bird count method has been used widely throughout New Zealand since the 1970’s to monitor the density & diversity of local bird populations.
The method is quite simple.
You stand quietly in one place for five minutes, & record all birds seen or heard in that time.
This method ideal in our native rainforests, where dense vegetation can make birds harder to see.
These counts are used as an index measure & used for comparisons in an area over time.
