Comments:
Canada Goose numbers building from 1100 h (approx 600) to noon (approx 1800); dissipating from noon onwards. As I was leaving, another wave was arriving in small "bundles." A pure flock of 22 Cackling (hutchinsii) flew overhead (from the WSW) and landed in the lagoons at 1137 h. I did three counts and tallied 21, 22, 22 respectively. At 1207, I noticed a "bundle" of 9 Cackling that I had previously overlooked. The bundle and the other 22 slowly began to coalesce and at 1224, all 31 flew SSE.

Flock of 22 hutchinsii flew in to lagoons at 1137. En masse high-pitched "yelping" very distinctive -- immediately drew my attention. At 1207, I noticed a "bundle" (tight-nit flock) of 9 slowly coalescing with the original flock of 22. At 1224, all 31 flew SSE out of view. A single Canada was trailing, offering a nice study of flight style (shallow + very hurried wing beats) and wing-beat frequency; the cacklers were nearing a 2-1 ratio of wing-beats compared to the Canada.

As good an example as I've seen of an adult tundrius bird. Very pale underparts and upperparts; needle-thin malar stripe. Flushed Killdeer and other shorebirds just after I arrived (1110 h).
