Botswana: Drought Affects Bird Migration
Botswana’s total number of birds recorded in November 2015 is lower than the number recorded in 2014, with a decrease of 32 percent reported due to drought, an official said Wednesday.Birdlife Botswana project officer Keddy Molefi said the drought indicator species – the Red-billed Qualea – recorded an 80-percent decrease in 2015.
He noted that various bird species migrate in response to the amount of rainfall in a country.
“High rainfall amount means high number of birds for the Red-billed Quelea. Seed-eater numbers has generally gone down and insect eater numbers has gone up,” he said.
