Galapagos Land Birds during the First Rains of Hot Season: Birders Get Ready!

Probably the most astounding fact that doesn’t get mentioned enough about the Galapagos Islands is that virtually all of the amazing wildlife can be seen year-round! Depending on what time of year you choose to visit, you might find the unique species of Galapagos either courting, mating, building nests or laying eggs. When it comes to land birds in Galapagos, amazing changes in behavior and color occur with the arrival of the first rains during the hot season. Some light drizzles start as early as December – a transition month between the dry and the hot season – while the month of January serves as the prime time for many of the Galapagos’ most iconic land birds to start to awaken as they spread their majestic wings in favor of the budding and beautiful flora. In this blog, we invite you to let yourself be taken away by the music of the first tropical rains that come drizzling in with the hot season as you open your eyes wide to soak in the wonderful features and behavioral patterns of these Galapagos land birds.

First Rains of the Hot Season: Hello Lunch Time!

Almost every land bird species depends on the rainy season in order to survive, especially the ones that inhabit the arid zones of the islands. Life needs water to thrive and rainfall is the first step in every living creature’s food chain.


When the rain comes, there are three different patterns of vegetation growth:

  • Plants that remain dormant during the dry season and start growing once the rainfall starts.
  • Plants that live only during the rainy season and then perish.
  • Plants that stop their photosynthesis during the dry season and turn a brown-grey color until the rain comes back, at which point they begin to photosynthesize again.

When the vegetation starts to make its big comeback in Galapagos during this time of year, some land birds and insects – some of which were dormant as well – start coming out and feeding on the young leaves and budding flowers of the blooming plants. What does this entail? Bugs love to feast on the vegetation, and Galapagos land birds love to feast on the vast array of Galapagos bugs that are zipping around during this period (note: some birds will only feast on the plants). What this entails is an elevated level of activity during this period.

This “ecological system” in Galapagos is specifically designed to encourage birds to reproduce when, and only when, they have food available. The flourishing flora throughout the Galapagos Islands during the first bit of rainfall means that consumable sources of energy are about to emerge, which almost immediately triggers unique changes in the behavior for Galapagos land birds. These changes can manifest themselves in the following ways:

  • Courtship behavior
  • Reproduction
  • Foraging
  • Raising their young

The peak of reproduction periods for Galapagos land birds is when rainfall reaches its highest levels, which typically occurs sometime in the middle of the hot season.

What happens to Galapagos Land Birds after the First Rains?

Once again: with abundant food levels comes the great desire to want to make the most of it, which is to say – reproduce. As a result, Galapagos land birds invest a lot of the energy they consume into making themselves look as extravagant and eye-catching as possible to attract potential mates.

In addition to this, Galapagos land birds will begin to flaunt their feathers in unique ways, given that simply having beautiful feathers and the mere virtue of being “alive” won’t cut it for the females. The females need and use these behavioral cues to decide on whether or not to say “yes” to the males’ gambits and courtship displays.

Sometimes these behaviors manifest themselves in ways that see Galapagos land birds turning into engineers and making fake nests for their potential mates (which could be more-or-less seen as a “test drive” of their abilities as a compatible and worthy mate).

Galapagos finches have a series of different feathers (primary, secondary). During the rainy season, some of the finches’ most important feathers are replaced with extravagant/showy feathers. The beak is also another feature of theirs that changes, transitioning from beige to a shiny black.

Even though most species are cryptic or melanistic – an adaptive behavior in which the animal produces no color to attract partners or scare predators – others, like finches, go all out during the rainy season. The finch is probably the Galapagos land bird with some of the most evident physical changes.

Galapagos Hawks

Galapagos hawks are polyandrous. One female has several males. When the rains start, the female will find the best spot/territory. In the case of these Galapagos land birds during the first rains of Hot Season, the females will find the best piece of territory a little before the rainy season begins and have the males come to her. The time this courtship behavior as such so that there’s an abundance of food available for when their offspring are born.

Here’s a list of Galapagos land birds that are predominantly active during the first rains of the hot season in Galapagos:

  • Mockingbirds
  • Galapagos dove
  • Galapagos short-eared owl
  • Galapagos barn owl
  • Dark-billed cuckoo
  • Vermillion fly-catcher
  • Galapagos fly-catcher
  • Paint-billed crake
  • Galapagos rail
  • Yellow warbler
  • Herons and egrets
  • Galapagos Martin

Because the rains last around 4 months, this means land birds have to be fast if they want to find a mate and reproduce. It all comes down to the food surplus generated by the rains. This is also the reason why during special meteorological events such as La Niña, when rain is scarcer, lands birds tend to be less successful when trying to reproduce. Only the best and strongest ones will be able to produce offspring, which also works towards improving the species gene pool. On the other hand, during El Niño, when rain can last up to 8 months, there is such an excess of food that the situation can turn promiscuous. For example in the case of the finch, scientists have observed one of the few situations in which natural hybridization happens!

A Font of information, Klaus has spent decades in the field, leading tours in the Amazon, Andes and Galapagos Islands. He hung up his guiding boots a few years back and now creates itineraries for the tour operator, Metropolitan Touring. Adrift in the Pacific Ocean, hundreds of miles from mainland South America, Galapagos is one of the most biodiverse locales on Earth.

Cruise Critic

Santa Cruz II is a replacement for the much-loved Santa Cruz, which plied the waters of the Galapagos for 36 years. It is not a new ship; it was built in 2002 and sailed as Mare Australis under the Australis cruise brand, operating expedition cruises around Cape Horn and to Antarctica. Metropolitan Touring bought the ship in 2015 and completely refurbished it, launching it as Santa Cruz II in October 2015.
