The authors then presented two bowls to the vultures, one with red soil dissolved in water and one containing only water. More than 20% of the birds visiting the feeding station then dyed their heads, neck and chest feathers with the red soil, while only one bird took a bath in the bowl with clear water. Mud bathing was done by both males and females, immature birds and even recently fledged young.<\/p>\n<p> However, not all birds died their heads &#8211;\u00a0 whereas some birds were highly attracted to the mud, others showed very little interest, and there was also a wide variety ion the extent birds dyed their feathers.<\/p>\n<p> You can see some videos of the species mud bathing at the links below.<\/p>\n<p> van Overveld, T. 2017a.
