Tiger territories are not exclusive. Several tigers may follow the same trails at different times, and a male's territory usually overlaps those of several females. Both male and female tigers spray bushes and trees along their route with a mixture of urine and scent gland secretions. This is a way of declaring their territory. They also leave scratch marks on trees, and urinate or leave droppings in prominent places.
Most tigers are tawny brown in color with dark stripes and whitish stomachs.
Reports and records indicate however, that a few wild tigers have been seen in unusual colors, including all white and all black. White tigers are not a separate subspecies of tiger, and they are not albinos, they are just white-colored Bengal tigers. White tigers are only born when two tigers that both carry the unusual gene for white coloring mate - their color is caused by a double recessive allele. A Bengal tiger with two normal alleles or one normal and one white allele is colored orange. Only a double dose of the mutant allele results in white tigers.
