DEFINITIONS

AMAUROSPIZA
(Cardinalidae; Ϯ Blue Seedeater A. moesta concolor) Gr. αμαυρος amauros  dark; σπιζα spiza  finch, identified by most authors as the Chaffinch  < σπιζω spizō  to chirp; "56. Amaurospiza *) concolor n. gen. et n. sp.   A. minor, unicolor coerulescente-ardesiaca; loris caudaque nigris; rostro pedibusque nigrescentibus.  Der ganze Vogel ist schwärzlichgrau, über und über matt graublau angeflogen, etwas lebhafter an der Oberseite und den kleinen Flügeldecken, weniger an den schwarzbraunen Schwingen und fast gar nicht an den Zügeln und dem Schwanze, welche fast ganz schwarz sind. Schnabel und Füsse sind gleichfalls schwärzlich.   ...   Der Vogel passt zu keiner der bekannten Gattungen und ist daher als Typus einer eigenen Gruppe zu betrachten.  Unverkennbar ist die Verwandtschaft mit den vorhergehenden Gattungen und findet Amaurospiza seine natürliche Stellung am besten zwischen Volatinia und Cyanospiza.   ...   *) Von αμαυρος, nicht hell, nicht glänzend, düster."

SUBSPECIES

Blue Seedeater (Slate-blue)
SCI Name: Amaurospiza concolor relicta
relicta / relictus
L. relictus  relict, isolated  < relinquere  to leave behind.
● The Slate-blue Seedeater of central Mexico was originally described in Amaurospizopsis, but allied to Amaurospiza of the distant rain-forests of Panama (Amaurospiza).
● The Relict Gull was described from the Mongolian Gobi as an isolated subsp. of the Mediterranean Gull Larus melanocephalus (Larus).
● The Alpine form of the Northern Nutcracker was considered specifically distinct, but allied to the form from Scandinavia (syn. Nucifraga nucifraga).
● This form of the MountainTailorbird is restricted to an isolated area of montane forest on Peleng in the Banggai group, Indonesia (subsp. Phyllergates cucullatus).
