U.S. Fish Wildl. The following summary of this report was published in Avery, et al 1980. It reports of a bird kill on only one night but the study seems to have been initiated because large kills had been reported on previous occasions. On 14 August, two transmitting stations in Maine were visited to collect information on possible bird mortality. Actual totals are likely much higher because scavengers clean up many bird carcasses during the evening before kills can be tallied.
Broadcasting is supposed to benefit communities.
One the one hand, it is nice that the FCC is promoting broadcasting of digital television from towers. As far as I know, the information content will be the same. Companies like Harron get caught in the middle and it is important to understand their perspective. They are in a competitive market and, even if they do have a clue about songbird mortality from their towers, they are not likely to take mitigative measures unless their competition does. Then one or another broadcast company can capitalize on bird-friendly broadcasting, and if the ratings swing, then the other broadcast companies will follow.
