Hi Andrew
Can you confirm that's 7000 (not 700)?
That amount of shags flying in would be an impressive sight

cheers

the actual count was 7180. I do monthly counts for Environment Canty and they peak at 6000-7000+ at this time of year. I think its by far the largest spotted shag roosting flock anywhere. Here's a pic of most of the flock.

There were 3 Otago Shags amongst c.7370 Spotted Shags at the roost at Ashburton Rivermouth this evening. These were 2 bronze phase birds and an adult pied phase (so birds different to the juv pied phase seen on my census last month).

A heads up to people visiting places that are night roosts for Spotted Shags on the Canterbury Bight coastline - eg; Timaru Harbour, Rangitata Rivermouth, Rakaia Rivermouth, etc. I reckon small numbers of Otago Shags now reach South and Mid Canterbury waters well north of the traditionbal limit about opposite Lake Ki-Wainono, and they can be potentially seen within a half hour or so of sunset when they join Spotted Shags at favoured night roosts. So, please have a look if anyone has a chance and report what you find?

Here' s some pics. Although the photos don't show it well, the pinkish legs and feet were very obvious under the brightness of the setting sun.

3 Otago Shags at Ashburton Rivermouth today amongst a flock of 10,000 Spotted Shags. A pretty impressive sight!! Spot the pied morph in the centre of this pic...... a small pin in a very big haystack. The other two were juv bronze phase birds.

I'm shocked at how few people have a Stewart Island Shag on their Canterbury Life List; Timaru's Inner Harbour is a really easy place to find one
