Falcons Order FalconiformesFamily FalconidaeFalconidae is a family of diurnal birds of prey.

In diurnal solar houses, the storage is designed for one or a few days.

Many species are diurnal and visit flowers for pollen and nectar, or to browse on the petals.

These cycles are often affected by changes in sleep cycle (too much or too little), diurnal rhythms, and environmental stressors.

The environmental affects may include diurnal temperature cycling, vibration, shock, humidity, solar radiation, precipitation, sand dust, salt spray and electromagnetic radiation.

The Egyptian mongoose is diurnal and lives in small groups of 1 7 animals, usually consisting of a male, several females, and their young.

Diurnal lemurs are visible during the day, so many live in groups, where the increased number of eyes and ears helps aid in predator detection.

Similarly, the 23 degree tilt of the Earth s axis about which the geomagnetic pole rotates with a diurnal variation, changes the daily average angle that the geomagnetic field presents to the incident IMF throughout a year.

It is not known how the diurnal eagles catch so many of the nocturnal colugos, which are thought to spend the greater part of the day curled up in tree hollows or hanging inconspicuously underneath a branch.
