Id def prefer to call at night for many reasons. To start with, I personally have way more fun at night; most people are at home in bed and its very quiet out and about. The suspense when walking in the dark to the stand and not knowing what is out there is awesome. The continual suspense of scanning that light looking for those lil eyes is great.
Predators seem to be more active at night, therefore, I seem to be more productive night calling.
Its easier to make a blooper on the set up and still be productive at night for me. Case in point, If i dont have good cover and Im sitting on a wide open hill side, in daytime it would prob mean no yotie, at night he cant really seem me as well so cover is not as important; least in my experience. My movement is concealed much better at night, I feel, giving me the advantage.
Predators seem to come stronger to the call, and hang up less at night, least in my experience.
Does it present challenges? O YES! Plenty of them, but thats what makes it so great.
