The Case of the Second Kewick
Recorded from 12:00 26 August 2026 to 11:59 27 August 2026
The real wildlife-monitoring record behind this episode. BirdNET proposals and observations are presented with their original uncertainty notes; character assignments remain fictional.
2026-08-26 · 12:00:54-12:57:52 BST
European Robin; Common Chiffchaff; Common Magpie; Dunnock; Goldcrest; European Goldfinch
Detections: 16; 22; 2; 2; 1; 5 Confidence: 0.55-0.99
48 proposals in the first local hour of the episode. All labels are BirdNET proposals; overlapping activity cannot establish individual counts.
2026-08-26 · 13:00:00-13:59:59 BST
Coal Tit; European Robin; Common Chiffchaff; Eurasian Blackbird; Blue Tit; Common Magpie; Eurasian Jackdaw; Eurasian Nuthatch; European Goldfinch
Detections: 36; 16; 8; 4; 2; 1; 1; 1; 3 Confidence: 0.51-1.00
72 proposals. The four Blackbird proposals support Blackbird activity, not sex or individual identification.
2026-08-26 · 14:00:00-14:59:59 BST
European Robin; Common Chiffchaff; Eurasian Nuthatch
Detections: 17; 13; 2 Confidence: 0.56-1.00
32 proposals; the continuing Robin activity does not identify a particular Robin.
2026-08-26 · 15:00:00-15:59:59 BST
Common Chiffchaff; Common Magpie; European Robin; Goldcrest; Long-tailed Tit
Detections: 15; 4; 3; 1; 3 Confidence: 0.38-1.00
26 proposals; four Magpie proposals support Magpie activity, not Gary's factual identity.
2026-08-26 · 16:00:00-16:59:59 BST
Goldcrest; Long-tailed Tit; Common Magpie; European Goldfinch; Eurasian Blue Tit; Common Chiffchaff; Eurasian Wren
Detections: 12; 5; 4; 3; 2; 4; 1 Confidence: 0.60-0.99
31 proposals. Long-tailed Tits are not Teeny Tiny Bird.
2026-08-26 · 17:00:00-17:59:59 BST
European Robin; Common Chiffchaff
Detections: 23; 9 Confidence: 0.48-0.99
32 proposals. This is the immediate lead-in to the early-evening sequence.
2026-08-26 · 18:06:38-18:33:35 BST
Common Chiffchaff
Detections: 5 Confidence: 0.62-0.99
Five BirdNET proposals in early evening. No recordings were reviewed for this species in this episode; labels remain BirdNET proposals.
2026-08-26 · 18:16:15-18:22:30 BST
European Robin
Detections: 4 Confidence: 0.53-0.97
Four early-evening Robin proposals. They do not identify Batman or establish a number of Robins.
2026-08-26 · 18:23:12-18:32:20 BST
Coal Tit
Detections: 16 Confidence: 0.89-0.98
Sustained Coal Tit-labelled run. Repeated windows can be a continuing vocalisation; Teeny Tiny Bird is not applicable (reserved for Blue Tit).
2026-08-26 · 18:49:03-19:09:24 BST
European Robin; Eastern Gray Squirrel; Eurasian Jackdaw; Eurasian Blue Tit
Detections: 1; 1; 1; 1 Confidence: 0.90; 0.96; 0.99; 0.83
Chronological isolated proposals: Robin 18:49:03; Grey Squirrel 18:49:50; Jackdaw 18:54:15; Blue Tit 19:09:24 BST. The squirrel is one high-confidence detection, not evidence of repeated or covert activity.
2026-08-26 · 19:12:08-19:32:51 BST
European Robin; Eurasian Jackdaw; European Goldfinch
Detections: 3; 5; 2 Confidence: 0.59-0.89; 0.91-0.99; 0.95-0.97
Robins at 19:12-19:15, Jackdaws at 19:17-19:32, and Goldfinches at 19:24 and 19:29 BST. Overlap does not provide a head count or an individual identity.
2026-08-26 · 20:05:26 BST
Common Raven
Detections: 1 Confidence: 0.93
Single BirdNET proposal marked correct in the supplied archive. This supports the species label for the event only.
2026-08-26 · 20:17:41-20:29:00 BST
European Robin
Detections: 6 Confidence: 0.58-0.84
Six Robin-labelled detections in twelve minutes; unverified BirdNET proposals.
2026-08-26 · 20:31:24-20:31:56 BST
Common Magpie
Detections: 2 Confidence: 0.90-0.93
Two sequential Magpie-labelled windows. Neither establishes Gary's individual presence or a group.
2026-08-26 · 21:07:06-21:13:24 BST
Tawny Owl
Detections: 9 Confidence: 0.80-1.00
Nine closely spaced Tawny Owl detections, marked correct in the supplied archive. Current acoustic continuity notes identify the bout as the distinctive raspy juvenile-type caller, provisionally Marlboro Junior. This is a caller-type interpretation, not proof of a particular individual.
2026-08-27 · 01:30:41-01:40:38 BST
Tawny Owl
Detections: 18 Confidence: 0.89-1.00
Longer owl bout. Direct comparison in supplied continuity notes supports Harold-type signatures first, Marjorie-type signatures later, and an acoustically distinct clean kewick-type Caller C around 01:32 BST. Caller C is provisionally Joline; sex, age, separate-individual status, and relationships remain unproven.
2026-08-27 · 05:26:28-05:58:52 BST
European Robin; Eurasian Wren; Common Magpie
Detections: 30; 2; 1 Confidence: 0.40-0.98; 0.70-0.78; 0.96
Dawn sequence: 30 Robin proposals, Wrens at 05:55:20 and 05:58:41, and a Magpie at 05:56:31 BST. Co-recorded windows do not demonstrate numbers or identify Batman or Gary.
