Best Time to Go Birding in Colombia:

A Region-by-Region Guide

QUICK FACTS

Short answer	Colombia is a year-round birding destination — there is no bad time, only better windows by region
Drier windows	Dec–Mar and Jul–Aug across much of the country
Endemics	Resident year-round — you can find them in any month
Migrants present	Roughly Oct–Apr (boreal migrants from North America)
Wettest region	The Chocó/Pacific slope — rain possible any month, part of what makes it so diverse
Bottom line	Choose your window around target regions and species, not around avoiding rain

 

Best Time to Go Birding in Colombia: A Region-by-Region Guide

It is the first question almost every visiting birder asks us: what is the best time to go birding in Colombia? The honest, encouraging answer is that Colombia is a year-round birding destination. Sitting on the equator, it has no true summer or winter — only wetter and drier seasons that vary by region. With around 1,900 bird species and roughly 80 endemics, all of them resident, there is genuinely no bad month to come. The real skill is matching your travel window to the regions and target birds you care about most.

How Colombia's seasons actually work

Instead of temperature-based seasons, Colombia has rainy and drier periods driven by the movement of tropical rain belts. Broadly, much of the country sees drier weather from December to March and again around July to August, with wetter spells in April–May and October–November. But "drier" is relative: this is a tropical country, and a short afternoon downpour can happen in any month, anywhere. Crucially for birders, rain is not the enemy — overcast, humid conditions often mean better mid-morning activity and softer light for photography.

A quick season-by-region overview

Region	Best window	Notes
Western Andes & Cauca Valley	Dec–Mar, Jul–Aug	Reliable year-round; endemics resident. Our home base near Cali.
Chocó / Pacific slope	Any month (Dec–Mar drier)	Wettest region on Earth — rain is the price of its incredible diversity.
Central & Eastern Andes	Dec–Mar, Jul–Aug	High páramo best in drier, clearer windows for visibility.
Amazon & foothills (Putumayo)	Jun–Sep (lower water)	Drier months ease trails & river access into remote reserves.
Santa Marta / Caribbean	Dec–Mar	Driest in the north; excellent for the Santa Marta endemics.

 

The Western Andes & Cauca Valley — our home turf

The region around Cali, where we are based, is one of the most dependable year-round birding destinations in the country. The Cauca Valley dry forests and the humid slopes of the Western Andes hold their resident endemics — Grayish Piculet, Multicolored Tanager, Apical Flycatcher, Gold-ringed Tanager — in every month of the year. The drier windows of December–March and July–August make the mountain roads easier, but the feeders and hotspots produce regardless. This is why we can run our Essential Colombia Birding Tour and photography trips across most of the calendar.

The Chocó: embrace the rain

The Chocó bioregion on the Pacific slope is famously one of the wettest places on the planet — and that is precisely why it is so extraordinarily diverse. If your targets are Chocó endemics like Toucan Barbet, Velvet-purple Coronet, or the enigmatic Sapayoa, you should plan for rain in any month and pack accordingly. December to March tends to be marginally drier, but do not wait for a "dry" Chocó — it rarely comes, and the birding is superb regardless.

The high Andes & páramo

For the high country — the páramo above Bogotá, Los Nevados, and the elfin forests where you find birds like Buffy Helmetcrest and Green-bearded Helmetcrest — the drier windows genuinely help. Clearer skies mean better visibility across open páramo and safer high-altitude travel. December–March and July–August are ideal for our high-elevation targets.

The Amazon & eastern foothills

For the remote south-east — the Putumayo lowlands and the Andes-Amazon foothills on our Eastern Andes to Amazon expedition — the drier months of roughly June to September ease river levels and forest trails, making access to places like Isla Escondida more comfortable. That said, this is rainforest: humidity and showers are part of the experience year-round.

What about migrants?

If you would like to add North American migrants to your resident-and-endemic haul, the boreal migration window runs roughly from October to April. During these months, wood-warblers, thrushes, tanagers, and shorebirds from the north swell the lists, layered on top of Colombia's resident riches. For many visitors, December to March hits a sweet spot: relatively drier weather in key regions and migrants still present.

So, when should you come?

Our advice after years in the field: do not plan your trip around avoiding rain — plan it around your target regions and species. If you want the broadest, most comfortable all-rounder, aim for December–March. If the Amazon foothills are your priority, look at June–September. And if you are chasing Chocó endemics, come whenever you can and bring good rain gear. Whatever window you choose, a resident local guide who knows each site's daily rhythm will do far more for your trip than any calendar.
