Counting birds and insects to evaluate crops for game.

Since some crops left on the fields may be useful to increase the game birds presence we compared the presence of different species of birds and insects in a crops for game and the surrounding farm crops. Four plots of Sorghum mixed with Foxtail millet surrounded by grasslands were submitted to bird (Point counts followed by strip transects) and insect (Pitfall and sticky traps) counts. Total bird mass with the number of air insects were the parameters more influenced by the habitat improvement so that the number of air insects, might be routinely used by the game manager to evaluate habitat improvements.
