I was interested in both Ian & Richard's comments on these gulls. I've
been working on my gulls in recent years & now have some hope of
recognizing the less common species. The location Ian mentioned would
be Rte 358 between Canard & Hillaton (per NS Atlas). But the fields
there are so huge that the gulls are far away. The Fred Thomas Rd
mentioned by Richard is parallel to 358 & one block west, so to speak.
Its entire length is just the W side of that "square". I was on Fred
Thomas Rd this PM & must have caught a fresh dumping of poultry litter
or processed poultry waste. The "field' is much narrower here so the
gulls are not so far away.

I was able to photograph the whitest Glaucous Gull you'll ever see. I
presume it's a first cycle bird, late winter, bleached to the max
(photo 34.12 Howell & Dunn). There are 3 photos & you can see that any
colour should have been captured, as per the gulls around it. Any
correction will be much appreciated.

I also photographed one Lesser Black-backed Gull. These 2 birds were
the only members of their species that I noted. I was likely there
30-40 minutes.

I also enjoyed the beautiful Redhead at the Port Wms sewage pond.
Inexcusable, but this was the first time I looked for it.
