๐ฆโฌ American Crow โ Species ID Dossier
Caption / Post body:
That "CAW CAW CAW" from the parking lot oak? Probably an American Crow โ but not definitely.
Swipe through all four cards to know when it's actually a Raven (bigger, deeper "cronk," wedge tail) or a Fish Crow (same size, but says "uh-uh" instead of a clean caw).
The crow's black isn't just black โ in good light, that plumage flashes blue-purple iridescence. The bill is stout with a faint hook. The tail fans out round instead of tapering to a point.
Four cards:
โ Perched portrait with field-mark callouts
โก Dorsal + ventral flight view
โข CAW mnemonic + amplitude pattern
โฃ Crow vs. Raven vs. Fish Crow comparison

Large bold mnemonic display "CAW! CAW! CAW!" โ phonetic breakdown /kษห/ ร 3โ9 repeats. Minimal waveform-style spectrogram: 4โ5 bar clusters decreasing in height left to right (amplitude decreases per caw). Three call-type pill badges: Contact Call / Alarm Call / Assembly Call. Frequency range ~500โ800 Hz. Behavioral context: Alarm = rapid staccato | Contact = evenly spaced | Territorial = long series.

Three-panel gouache comparison grid:
- American Crow (17โ21 in): Fan tail, stout bill, CAW call
- Common Raven (22โ27 in): Wedge tail, curved culmen, heavy bill, CRONK call, visibly larger
- Fish Crow (14โ16 in): Slightly smaller/slender, UH-UH nasal call, coastal/SE range

Ornithological Notes
Morphology: 17โ21 in (43โ53 cm), wingspan 33โ39 in, weight 11โ22 oz. Entirely glossy iridescent black (blue-purple sheen in good light). Stout heavy straight bill with slightly hooked tip. Fan-shaped/rounded tail (key vs. Common Raven). Sexes identical in plumage; males slightly larger.
Flight: Long, broad wings; spread primary fingers at wingtips. Steady deep rowing wingbeats, less buoyant than raven. Tail fan-shaped in soaring. Direct purposeful flight.
Vocalizations: Primary call "CAW-CAW-CAW" โ /kษห/ repeated 2โ9 times, amplitude decreasing per caw. ~500โ800 Hz fundamental. Alarm: rapid staccato. Contact/flock: evenly spaced. Territorial: longer series. Assembly: when gathering at roost.
Key ID points vs. look-alikes:
- vs. Common Raven: smaller, fan tail (not wedge), plain "CAW" (not deep "cronk"), less curved culmen
- vs. Fish Crow: larger, clean "CAW" (Fish Crow says nasal "uh-uh"), slightly heavier bill
- vs. European Starling: much larger, longer tail, no triangular wing shape, doesn't flock in murmurations
