Pigeon: 12-15 inches tall, blue-gray with a white rump, has iridescent feathers on head and neck. Can also have white, brown or gray plumage

The Pigeon is one of the most loved and equally despised bird species. Pigeons are nuisances around our homes and businesses due their nesting and defecation. Aside from the unsightly results to buildings from their presence, they can also transmit numerous diseases.

Starling: 7-8 inches tall, dark chunky, muscular bird. Plumage varies by season. In winter the bird will display a highly speckled iridescent coat and a dark bill. In Summer the bird's coat dulls and has far fewer speckles.

Starlings make mud nests under the eaves of homes and buildings. These nests can become quite numerous on structures with large populations of these birds. Removal of these nests can be very expensive and very labor intensive. When not removed, these nests can become reservoirs for other insect pest species, bats or becomes focal points for diseases.

Grackle: 12-16 inches tall, black plumage that is tinted green/blue or purple iridescent. Glossy purplish heads and neck. They have "v" shaped tails that are very distinctive.

Grackles are the largest of the pest species listed here. They can accumulate in great numbers. Their loud and disturbing noises can distrupt sleep schedules and make duties at offices more challenging. Grackles can be very aggressive to both other bird species, animals and people. It is not uncommon to see Grackles "dive-bombing" perceived threats in their territory.

Woodpecker: 7-15 inches tall, with brightly contrasting coloration. Many males have some red on their heads. Nearly all woodpeckers have some black and white marks.

Woodpeckers are troublesome for several reasons. They can do significant damage to a structure through their "hammering" behavior. Facia boards and soffets are often left with holes after Woodpecker activity. Woodpeckers will also attempt to "hammer" through metal sheeting around chimneys and other metal structural members. The resulting noise can be both startling and bothersome.
