Descriptionedit
It ranges from 17 to 21 cm (6.7 to 8.3 in) in length and weighs 24 to 49 g (0.8 to 1.7 oz). All subspecies are some shade of olive-green. The call is a repeated series of three to four notes.[2]
Dietedit
The Inaccessible Island finch eats mainly seeds and insects. The plants consumed vary by subspecies. N. a. acunhae eats the seeds of Spartinia grasses, such as Sporobolus arundinacea, as well as Carex. N. a. fraseri feeds on Nertera. N.a. dunnei feeds on Phylica. All subspecies of N. acunhae use flies as their main source of prey.[4]
Reproductionedit
It breeds from November to February. They are usually monogamous, and partners remain together for successive breeding attempts. Females lay one or two eggs in a cup nest close to the ground.[2]
