Also, look for inviting habitat nearby such as convenient nest sites and open trash. In either situation, the adults may wind up abandoning the nest altogether.In most places in this summer of 2020, nesting birds didn’t have to contend with unusual cold, but exceptional heat could have been a problem in some areas. But their habit of packing nesting material in stove, dryer and fan vents may prevents use of the vents—a more serious problem.Excluding house sparrows from places we don’t want nests before they build is the first—and best—approach.
