Swainson's Thrush

How to find it

Look low, in shaded forest, at forest edges and in dense vegetation, and expect to be patient, since the muted brown colour and spotted chest blend into the forest floor. Listen first: this thrush is heard far more often than it is seen. Check berry-bearing shrubs, where migrants often feed alongside other thrushes and sit a little higher than Veeries or Hermit Thrushes. Choose quiet wooded spots rather than busy places, because the bird tends to avoid people and buildings. Watch the leaf litter beneath the shrubs too, since it searches the ground for insects.

How to recognise it

Swainson's is a medium-sized thrush with a round head and a short, straight bill. It is olive-brown above and white below, with brownish spots on the throat and breast, and the breast also carries a buffy wash. The best field mark is a large buffy eyering that extends forward to the bill, giving the bird a spectacled look.

The form that reaches Costa Rica along the Pacific coast route is the one called Russet-backed. It is rustier above than the inland birds, with a thinner, paler eyering and medium-brown chest spots. Its tail matches its back in colour, which helps when you compare it with other brown thrushes.

Behaviour and diet

Wintering birds are generally solitary. They forage on or near the ground, looking for insects and other small invertebrates among fallen leaves, and they also eat berries and fruit. It spends much of its time low down, not in the canopy.

During migration these thrushes often feed on berry-bearing shrubs alongside other thrushes, and they tend to feed higher in the vegetation than Veeries or Hermit Thrushes. On its wintering grounds the bird tends to keep away from buildings and human activity.

Where it lives

In Costa Rica it travels through and winters in shaded forest, forest edges and dense vegetation. It searches leaf litter and low plants for insects and berries. A Costa Rican birder describes it as fairly abundant in some areas, and has seen it in urban woodlots as well as in the rainforest of Braulio Carrillo National Park.

A migration guide points to regions such as Arenal and La Fortuna, the Central Valley and highland forests, and the Osa Peninsula, though the thrush is not tied to any one of them. On the Osa Peninsula the habitats include wet forest, premontane wet forest and moist forest.

When to see it

A general Costa Rica migration guide says many songbirds arrive or pass through from late August to October, many stay November to February, and many head north again March to May. On the Osa Peninsula, spring passage rose in late March and peaked in mid-April, with nearly all birds gone by the first week of May.

Similar birds

Some people mistake it for a young Clay-colored Thrush, which belongs to the same family, Turdidae. The hardest lookalike on migration is Gray-cheeked Thrush, which has a cold gray face and only a faint pale area behind the eye, while Swainson's shows a strong buff face with a full eyering. Hermit Thrush also has a bold eyering, but its reddish tail contrasts with a duller back. Veery is warmer reddish-brown with faint spots and a weak eyering, and Wood Thrush is larger and chunkier with big triangular spots.

Names and lore in Costa Rica

Costa Ricans commonly call it Conchita, alongside the AOCR name Zorzal de Swainson.

Status and conservation

Swainson's Thrush is a migrant on the AOCR list, and the IUCN lists it as Least Concern.

Photography tips

Patience matters more than gear. Settle quietly near a fruiting shrub at a forest edge or beside a shaded trail and let the bird come out to feed. Its plain brown back and spotted chest hide it well, so listen for the song and the flight peep, then scan low vegetation and the leaf litter.
