Given a reference text about the golden-green woodpecker, tell be how big they are.
The golden-green woodpecker (Piculus chrysochloros) is a species of bird in subfamily Picinae of the woodpecker family Picidae. It is found in Panama and every mainland South American country except Chile and Uruguay.

The golden-green woodpecker is 18 to 27 cm (7.1 to 11 in) long and weighs 55 to 91 g (1.9 to 3.2 oz). Males and females have the same plumage except on their heads. Males of the nominate subspecies P. c. chrysochloros are red from forehead to nape, have olive green from the lores around the eye and onto the side of the neck, and successively a pale yellow stripe, a short red malar band, and an olive green stripe below that area. Their chin and upper throat are yellow. The nominate female has no red on its head; its forehead to nape are olive and it has an olive-brown malar area. Nominate adults have olive green upperparts. Their flight feathers are darker olive-brown and their tail dark olive-brown. Their underparts are pale yellow-buff with olive-brown bars. Their longtish beak is dark gray to blackish with a paler base, their iris white to bluish white, and the legs grayish green. Juveniles are generally duller than adults and have less well defined barring on their underparts.

Subspecies P. c. xanthochlorus is smaller and brighter yellow than the nominate, and the female has a yellow crown. P. c. capistratus is very large and a darker olive green above than the nominate, and has less red in the malar area, a barred throat, and greenish white instead of yellow buff on their underparts. P. c. paraensis is intermediate in size. Its cheek stripe, throat, and underparts' base color are cinnamon-buff. Males have a green, not red, malar, and females have a greenish yellow crown. P. c. laemostictus is large and rather dark, with a plain whitish throat. P. c. polyzonus is also large, with a pale yellow cheek stripe and throat and a yellow base color on the underparts
The golden-green woodpecker weighs between 55 and 91 grams and is between 18 and 27 centimeters long.
