Lanceolated Monklet

Micromonacha lanceolata

In Spanish: Monjito Rayado

  • Resident

A tiny streaked puffbird of Caribbean foothill forest, heard before it is seen.

Where to see itTrips that find it

The Lanceolated Monklet is a tiny, round, brown puffbird, 13 to 15 cm long, and a Costa Rican guide blog called it the hardest puffbird to see in the country. Its behaviour and uncommon status make it hard to spot, and guides often find it by hearing it first.

In Costa Rica it lives on the Caribbean slope, and its range there continues south into west central Panama. On trips we build around the Turrialba foothills, the Río Tuis valley below one lodge is where the guides go for it, and a guided day in the valley's forest reserve looks for tanagers and for the monklet if the guide's luck holds.

One Costa Rican birder describes it as a bird that hides in plain sight, and he searched one site for over ten years before getting perfect views.

Where to see it

How to find it

Guides often find the monklet by hearing it first, so listen for the rising, thin whistles. Costa Rican guides whistle an imitation of the song and listen for a reply, and one does this in foothill ravines and rivers and sometimes gets an answer. Scan mid-level perches at forest edges and clearings, since it hunts from about 4 to 8 m up. Because it sits still, extra pairs of eyes in a group help. A morning in the Río Tuis valley does not always succeed, so it helps to allow more than one try.

How to recognise it

Look for a tiny, round, brown puffbird, 13 to 15 cm long. It has a stout black bill with white bristles and whisker tufts, and pale underparts boldly streaked with black. The forehead is white, and white lores look like spectacles. The centre of the belly is unstreaked, and the vent area has an ochre tinge. The tail is dull brown with a pale tip, dark brown above and gray below. The legs and feet are olive-gray. Overall it is a small, squat bird with a big head and brown upperparts, and a well-seen monklet is unlikely to be confused with other birds.

Behaviour and diet

The monklet perches quietly and can stay still for long periods. It is often seen loosely joining flocks in the sub-canopy, which makes it easy to overlook. It hunts from a perch about 4 to 8 m up, and from there it flies out to catch insects. It feeds on insects and berries. Like other puffbirds it sits still, and puffbirds also move the tail back and forth like owls do. Nesting has been documented in southeastern Peru, where it uses a tunnel dug into an earthen bank and lays two white eggs.

Where it lives

In Costa Rica the monklet favours wet forest at lower middle elevations, usually on the Caribbean slope. Across its whole range it mostly occurs between 300 and 1,500 m, and has been found as high as 2,100 m. Range-wide it uses forest edges, clearings in mature forest, small forest patches and shade coffee plantations, and it tends to stay in the middle and upper levels of the vegetation. Costa Rican guides look in foothill rainforest, along streams and in mossy forest.

Similar birds

Puffbirds can be mistaken for pygmy owls because of their shape and colour, and both move the tail back and forth. A well-seen monklet, though, shows the white spectacles, brown upperparts and thick black streaks on white underparts.

Names and lore in Costa Rica

Costa Ricans call this bird Monjito Rayado, the name on the official Costa Rican list. Other Spanish names used elsewhere include Monjilla Lanceolada, Buquito Rayado and Chacurú Chico.

Status and conservation

The AOCR list marks it as a resident (R), and the IUCN rates it Least Concern, with a large range.

Photography tips

One photographer shot a monklet at 600 mm, with the bird perched quietly near a forest edge or clearing. Look for it there and let the group's extra pairs of eyes help, since it stays still.
