With a morning free (and encouraged by photo sets on Facebook) I decided on an early morning walk around Hickling NWT reserve. My first stop - the new vantage point over Brandon's Marsh - revealed that the FB posts were misleading: there wasn't a drop of water on the marsh! No water, of course, meant no waders or herons, and the same situation obtained all the way around: no water birds at all (if you don't count hundreds of raucous Canada Geese!) The scheduled ditch-digging and lowering of the water table had emptied the reserve.
Lots of Ruddy and Common Darters, as well as Black-tailed Skimmers, Migrant & Southern Hawkers and a few Shield Bugs: but that was it!
