The Bird Perch / Shag City
This popular bird perch is home to many black shags / cormorants at Sulphur Bay, Rotorua.

Sulphur Bay
Sulphur Bay, a 145 hectare wildlife refuge, sits in the south eastern corner of the volcanically formed Lake Rotorua. Sulphur Point, is the small headland protruding into the bay and has a Wildlife Sanctuary Protection status - the highest status of wildlife protection.

There are 63 bird species in the area - 45 are native and 24 are water dependant. Warmth, refuge and proximity of food are the most likely reasons birds gather in such large numbers. Birds found include: black and red-billed gulls, pied stilts, spur-winged plovers, NZ dabchick, shags, swallows, pukeko, black swans, mallard, herons, shags / cormorants, and the threatened banded dotterel.

A stream flowing into the bay features geothermal activity at its mouth; the origin of the warmth and murky sulphurous waters.

At the Sulphur Bay Wildlife area on Lake Rotorua, shore and water birds are exposed to natural H2S at concentrations of 125 to 3900 ppbV from continuous shore and lake sources. Nevertheless, 62 bird species, 45 native, have been recorded there.

Some, the Red Billed Gull and Little Black Shag, have initiated colonization within the past half-century. It is suggested that exposure to H2S at the levels reported here may be less of a biohazard than previously supposed.

Lake Rotorua
The name Rotorua derives from the Maori language: Roto means lake and rua means two
. Literally translated Rotorua means ‘second lake’. It was named by Maori chief Ihenga, as it was the second major lake he discovered while exploring the area.

Lake Rotorua is circular: 10 kms in diameter, 915 feet above sea level with an average depth of about 15ft. The lake is a shallow basin that slumped after volcanic activity emptied its magma chamber beneath. Formed some 100,000 years ago, it is the largest of 19, situated to the north-east of the city.

I didn't know about this place,but it sounds like an interesting spot.
Glad you managed to find at least one unobscured by those tangles of twigs.
Great image.
