Signs and tracks upgrade

Originally our tracks were built to give our volunteers access to do restoration work. Since our section of the gully has been opened up, the public have started to use the tracks for their recreation. We have now changed our focus. We have been putting a great deal of work into supporting public access to zone 1 of Mangaiti Gully by upgrading the tracks. At the Keswick end, where council has erected a gate, we have installed a bike rack, so cyclists can lock up their bike and go for a walk (photo 1). We have invested quite a lot on money on signs at all four entrance points. These signs include a colour coded map of all our tracks. The colour codes line up with corresponding coloured pegs along the tracks. (photo 2). This is all in line with Hamilton City Councils Nature in the City strategy of opening up the city’s natural areas for the public to enjoy.

Fledging time for our local birds

This time of year, tui fledglings seem to be everywhere and, harder to see, fledging fantails and grey warblers. This is a positive sign that we have a very successful rat and possum control programme that has been running since 2016 over the whole thirty hectares of Mangaiti Gully. Here is a video clip of a very young fledging tui (note the yellow still evident at the base of its beak) which was recorded by Tony Grey. It is surprising that it is foraging so well by itself and not relaying on it’s parents. The other video clip is of a fledging tui still learning to sing. The audio is not strong so you will need to turn up the volume on your device to full.

Morepork in nest box

This nest box was built from a Wingspan design (Link here: https://www.wingspan.co.nz/PDF/how-to-build-morepork_nest_boxes.pdf ) and installed in 2018 by a person who lived on the gully. He has since moved house. The bait line he serviced has been taken over by one of our volunteers. While doing one of these services back in November a morepork was noticed leaving the nest box. We then installed a field monitoring camera on a nearby tree. This camera recorded the progress of the two chicks and activity of the parents up to the successful fledging. Photo 1 was taken early in the evening while going to install the camera for the night. Note the camera bracket to the right of the bottom parent bird. Things of interest recorded were that both parents fed the chicks; other than only one mouse recorded, all the food supplied to the chicks were invertebrates, probably moths; repeat visits were very frequent (Video 1) although at times there could be a pause for half an hour or more. These rest periods tended to be in the middle of the night. Moreporks strongly defend a territory of 3.5 to 7.8 ha. The Mangaiti Gully system is 30 hectares so in theory it could support 4 to 8 breeding pairs so there is room for a few more boxes.
