9. January. Waitakere, Muriwai & Silverdale.
With all key birds now seen in New Zealand, I decided today to potter around the greater Auckland area, enjoying the spectacle of the Australasian Gannet colony at Muriwai, plus attempt to find some of the growing population of Sulphur-crested Cockatoos and, hopefully, locate a Australian Little Grebe, a species that has established a small population in the northern parts of North Island.
Locality one, the Waitakere Range, heavily forested hills only a few kilometres from my friend's abode and forming the heartland of the Sulphur-crested Cockatoo range. I had read reports of roosts in the valley below the Waitakere Golf Course, so that seemed a logical place to start ...except the road was closed due to Kauri dieback! Fortunately, the road was open as far as the golf course, so I parked there and wandered along its margins to the far side, loads of Masked Lapwings and Australasian Swamphens on the greens, plus Eastern Rosella flying over and Sacred Kingfishers at the edge of thickets. Down yonder, deep raucous calls echoed around the valley ...I knew what that was! And indeed, from the bottom of the gold course, scanning a line of tall trees opposite, a whole bunch of Sulphur-crested Cockatoos, at least 20 in all. Well that was quite easy ...and just to be nice, several then flew over, hanging out in vegetation around the gold course.
Next stop, the Australasian Gannet colony at Muriwai. Almost didn't bother with this site, but I am glad I did - a sometimes present Brown Booby didn't appear, but the sheer spectacle of the colony was impressive. Occupying slopes on the clifftops and spilling across a couple of adjacent rock stacks, approximately 1200 Australasian Gannets breed at this location, the sky thick with birds flying in and out, the colonies a polkerdot of these magnificent birds. With the closest birds mere centimetres away, and the colony at various stages from pairs with chicks a few days old to near full-grown, it truly was a sight to appreciate. And just for added appeal, along the trails either side of the headland, plentiful Rauparaha's Coppers active in the morning sunshine.
So, a pretty successful morning so far. With thoughts now turning to Australian Little Grebe, the most promising site seemed to be the Te Arai stormwater pools over on the Hibiscus Coast, reports suggesting there had been birds there in previous months. Annoyingly I had virtually driven past these pools at the beginning of my trip without knowing that they might hold Australian Little Grebe.
So off I went, a drive of about an hour, the destination adjacent to a rather busy road in a very suburban setting. Australian Magpies, Spotted Doves and Common Mynas in pastures and roadside, Australasian Swamphen and Pied Stilt on the first pool investigated. Manky Pacific Black Ducks on the second pool and just a single bird on the final pool ...but fortunately that single bird was an Australian Little Grebe! Happily diving and feeding, oblivious to cars and pram-wielding mothers in the immediate vicinity, this was a nice addition - my fourth grebe species of the trip, two of which are Australian vagrants.
And with that, after a relatively fruitless search for butterflies in an overgrown cemetery (four Monarchs, three Small Whites, plus two Sentry Dragonflies), I returned to my friend's place, the remainder of the day an easy-going affair, punctuated by a Shining Bronze Cuckoo in the garden and a nice visit to an old mine shaft to see its creepy inhabitants ...eight pretty impressive Cave Wetas.
