This image was taken using a GeoEye-1 satellite with a 0.5 m resolution sensor. No date is given as to when the image was captured but the image was taken in Kenya. The purpose of the image is to observe wildebeest migration. Although the image source does not specify when the migration occurs, it is well known that wildebeest migration usually occurs between June and October. However, this migration period is not definitive because seasons change may affect it. A great number of wildebeest leaves the Serengeti region of Tanzania when the rainy season ends and plains have dried out. During that period of time, the wildebeest herd crosses the Masai Mara river in Kenya and stays until October, at which point it crosses the river again to return to the Serengeti region. The image might be important to monitor wildebeest population growth or decline over time and it is also important to observe grazing patterns during this migration.
