Some good methods for moose calling include the cow communication grunt and bull grunt. Calling during the rut is one of the most effective methods to attract a moose.
Hunters often use the cow call late in September to attract a moose within shooting range. This sound is nasal melodic whine that many choose to augment with a megaphone. The bull grunt is particularly effective in mid-September, as mature bulls often become more aggressive prior to the rut season. This sound is similar to a deep "mu-wah," and hunters generally prefer to repeat it three or four times to get the desired results.
