A landslide caused by heavy rain struck in the municipality of Argelia in southern Cauca early on 25 April, 2020. One house was destroyed and others badly damaged. One person was injured.
Torrential rain caused flash flooding in other parts of the department earlier this month. On 16 April, flood waters raged through the streets of Santander de Quilichao, causing damage to homes and material possessions.

Comment: The explanation usually tossed out for these kind of events - that the birds may have been attempting to avoid an aerial predator - seems superficially plausible at first. However if this was really the case one might reasonably expect to see numerous examples and witness reports of mass fatalities like the above happening in the natural world every single day.
Clearly this is not the case.
The explanation just doesn' t fly.
Something odd is going on.
