Why Do Some Hunters Prefer Estrus Calls Over Cow Calls?

Estrus calls are designed to mimic the specific sounds made by a cow elk during the peak breeding season. These sounds are higher pitched and more nasal than the typical cow calls used for bugling. Research has shown that bull elk are more likely to respond to estrus calls, especially during the early season, when the bulls are actively searching for receptive cows. In fact, studies have found that up to 75% of bull elk will respond to estrus calls within a 1-mile radius. This is because the high-pitched sounds trigger a primal response in the bulls, causing them to search for the source of the sound.

Techniques for Using Estrus Calls Effectively

To use estrus calls effectively, hunters should begin by making a series of 3-5 high-pitched “clucks” or “chirps,” followed by a longer, more nasal “woo” sound. This sequence should be repeated every 10-15 seconds to mimic the sounds made by a cow in heat. Hunters should also use a “bugle” call every 30-60 seconds to help pinpoint the location of the responding bulls. When using estrus calls, it’s essential to be patient and persistent, as it may take 30 minutes to an hour for a bull to respond.

Tips for Determining Which Calls to Use

When deciding whether to use estrus calls or cow calls, hunters should consider the time of year, the location of the hunt, and the behavior of the elk. During the early season, when elk are actively searching for mates, estrus calls may be more effective. In the late season, when bulls are more focused on defending their territory, cow calls may be more effective. It’s also essential to consider the terrain and the type of elk present in the area. In areas with low elk populations or in dense cover, cow calls may be more effective due to the increased difficulty in pinpointing the location of responding bulls.
