Travel repeatedly with the same guide or operator, which is the strongest single relationship in this community, share sightings and conditions during a season, run photography groups, and return to the same window year after year. Operator repeat-client lists, specialist wildlife photography communities, and closed groups where sightings circulate during a window and are not shared outside it.

The run, the crossing, a bait ball, the aggregation, a superpod, the window, the hide, the sighting network, working a subject, a blank season. The windows themselves, which recur annually within a fortnight or so and are the closest thing to editions this row has.

A chain of windows rather than a season. June and July for the southern African sardine run.

July to October for the East African river crossings. October to January for the northern Norwegian orca and herring aggregation.

January to March for the Baja grey whale lagoons. March to July and June to September for the two main whale shark aggregations in different hemispheres.
