Until November 2020, migratory birds will arrive in the Aburrá Valley and other regions of Colombia, which come mainly from North America and continue to the south of the continent, seeking tropical climates, shelter and food away from winter. In March 2021, they will resume their path, this time towards their place of origin.
Some species are only passing through and others are established in cities. At this time it is common to see "clouds" of hundreds of black birds passing through the sky, usually composed of hawks, hawks and red-headed buzzards that, one by one, go down to rest or settle.
These flocks mainly include individuals of wide-winged hawk (Buteo platypterus), lobster hawk (Buteo swainsoni) and peregrine falcon (Falco).
Also, some small and medium-sized birds begin to arrive in gardens, feeding places and edges of streams, such as the warblers (of the genus Setophaga), the pirangas (of the speciesPiranga rubra, Piranga flava and Piranga olivacea), the American cuckoos (Coccyzus americanus), some flytraps of the genera Empidonax and Contopus and buchipecosos thrushes (Catharus rotteds)
In the Medellín river and the lakes and wetlands of the northern municipalities, some plovers and sandpipers (of the speciesTringa solitaria, Tringa melanoleuca and Actitis macularius), ducklings (spatula odds) and ospreys (Pandion haliaetus).
And it is also common to see and hear the blind chickens or roadguards of the speciesAntrostomus carolinensis y smaller Chordeiles, which are nocturnal insectivorous birds that live near paths or in green areas.
Although these visitors generally adapt well to our cities and urban ecosystems, they may crash into windows or buildings or find themselves fatigued on the ground, vulnerable to being run over, attacked by pets, or captured. The animals that are most frequently reported are American cuckoos (due to exhaustion), blind hens (due to exhaustion and attack by domestic animals) and thrushes (due to collisions). Some hawks and hawks are also attacked by people and domestic animals, so it is invited to report the mistreatment of this type of bird.
