Izu Robin (Larvivora tanensis)


Taxonomy

French: Rossignol des Izu German: Izunachtigall Spanish: Ruiseñor de las Izu
Taxonomy:

Erithacus akahige tanensis

Nagamichi Kuroda

, 1923,

Nishino-omote, Tanegashima, south of Kiu Siu, Japan

.

Hitherto treated as conspecific with L. akahige, but differs in its lack of black breastband (2); pale (yellowish) base to the lower mandible vs all-dark bill (1); lowland habitat and resident status vs upland habitat and migratory status (1); more stuttering, less trilled song, having an overall longer duration (1) but a shorter second trilled part (2) with fewer notes (ns[1]) delivered at a slightly slower pace and with a slightly larger frequency range#R. Populations of Larvivora on islands S of Kyushu have been attributed to this species (including in HBW) but in fact belong to L. akahige. Monotypic.
