Three species and several subspecies of red-wings are recognized,[42] but practically no difference exists in the habits of these forms either in nesting or feeding, except such as may result from local conditions. Most of the forms are found on the Pacific side of the continent, and may be considered as included in the following statements as to food and economic status. [42] Agelaius phœniceus (8 forms), Agelaius gubernator, and Agelaius tricolor. Many complaints have been made against the red-wing, and several States have at times placed a bounty upon its head. It is said to cause great damage to grain in the West, especially in the upper Mississippi Valley, but few complaints come from the northeastern section, where the bird is much less abundant than in the West and South. [Illustration: Fig. 14.--Red-winged blackbird. Length, about 9½ Inches.] Examination of 1,083 stomachs showed that vegetable matter forms 74 per cent of the food, while animal matter, mainly Insects, forms but 26 per cent A little more than 10 per cent consists of beetles, mostly harmful species. Weevils, or snout beetles, amount to 4 per cent of the year's food, but in June reach 25 per cent. As weevils are among the most harmful insects known, their destruction should condone some, at least, of the sins of which the bird is accused. Grasshoppers constitute nearly 5 per cent of the food, while the rest of the animal matter is made up of various insects, a few snails, and crustaceans. The few dragon flies found were probably picked up dead, for they are too active to be taken alive, unless by a bird of the flycatcher family. So far as the insect food as a whole is concerned, the red-wing may be considered entirely beneficial.
