Climate Safety: A safe birdhouse is snug and comfortable for nesting birds, without being subject to extreme heat or cold, rainy leaks or damaging winds. To keep a house safe from the weather. Choose a bird house design with ventilation holes in the upper part of the walls to circulate fresh air and prevent the house from getting too hot and suffocating or stifling chicks. If the design does not include ventilation holes, drill unobtrusive holes in the corners or sides of the house. Do not drill holes in the roof, however, where leaks could occur.
Most birds that can be attracted to feeders are insect or seed eaters. Insect_eating species, such as chickadees and woodpeckers, are attracted by animal fats or "suet." This can be obtained from the grocery store or trimmed from beef, pork, moose, caribou, or other wild meat. Fats that have a low water content are best in areas with severe cold, because they freeze at lower temperatures. Peanut butter, another fat, also attracts birds to feeders. Its sticky consistency occasionally causes problems for birds, so it should be mixed with melted animal fat and cornmeal or rolled oats. That expensive peanut butter will last longer if it is mixed with other ingredients, anyway.
