Urban lagoons: full and with birds arriving from the US | Lagunas urbanas: colmadas y con aves que llegan de EEUU

The natural water bodies of Coña Coña, Alalay, Quenamari, and Cotapachi serve as refuges for various species of flora and fauna. Their appearance has improved with the recent rains.

Cochabamba’s urban lagoons are filled with water and surrounded by wildlife, including birds that arrive from across the continent, such as swallows from North America.

Recent rains have allowed these natural water bodies to reach their maximum capacity, and some have even overflowed.

Bladimir Vargas, Municipal Secretary of Productive Development, Rural Affairs, and Environment for the Quillacollo Mayor’s Office, reported that the Cotapachi lagoon exceeded its limit after a long time.

A similar situation is observed at the Alalay lagoon, whose depth has tripled, according to information provided by Elvis Gutiérrez, Director of Environment for the Cochabamba Mayor’s Office.

The abundance of water in these lagoons—along with Quenamari and Coña Coña—has brought them back to life and is attracting a wide variety of bird species.

The most striking are the swallows. Ornithologist Cindy Veizaga explained that they are boreal migratory birds that have arrived from the United States and Canada.

She added that, during this season, the city typically receives many species, especially “altitudinal migrants,” which come from Tunari National Park—such as hummingbirds, for example.

The urban lagoons are also nesting grounds for birds from higher altitudes, like flamingos and ducks.

“Urban lagoons are very important because they provide refuge and feeding grounds for a large number of species like Fulica ardesiaca and Gallinula galeata, which are water hens that nest in the lagoons,” the expert emphasized.

She added that these spaces also serve as shelters for ducks and are stopover zones for migratory species like sandpipers, which feed along the shores of the lagoons.
