Every outing becomes a note: the date, the place, the weather, what was out, and which phase of the season it was in. The strip below is the year; the column under it is the last eight notes.
Each cell is a month. Lit cells hold published notes.
senescence
Eight tagged black cottonwoods at Luckiamute went from 30 per cent to 92 per cent leaf fall in thirteen days, the fastest fall of any tree on this reach, and the leaves are going straight into the river rather than onto the bank.
migration
A fixed 200 m walk at Jackson-Frazier on 15 October produced 63 sparrows of five species, against 11 on 24 September. The water table rose 14 cm in three weeks and the boardwalk is flooded at two points.
senescence
Six litter traps under Oregon white oaks collected 41 grams of dry leaf per square metre between 5 and 12 October, and the oaks were at 62 per cent leaf fall against 18 per cent for the same-day ash trees.
fruiting
A fruit transect at Oak Creek on 9 October found 340 rose hips at 31 per cent of the original crop and 96 crabapples at 74 per cent, and the birds working the two were different species in a fixed order.
senescence
One red-breasted nuthatch made 22 separate caches in 30 minutes of watching on 6 October, all of them in bark crevices between 2 m and 9 m up, and it revisited two of them within the half hour.
migration
One thousand one hundred and eighty Vaux's swifts entered an old brick chimney in downtown Corvallis between 19:06 and 19:38 on 3 October, a rate of 78 birds a minute at the peak, in the middle of the autumn migration for this species.
senescence
Twelve tagged vine maples at Alsea Falls averaged a colour score of 3.1 out of 5 on 30 September, a fortnight ahead of the bigleaf maples 200 m away in the same drainage, while the creek fell below 10°C for the first time.
migration
Four varied thrushes and a mixed flock of 34 birds were moving through the fog at the lower saddle on 27 September, three weeks after the first darner flight on the same ridge and in the same north wind.
