Well, it’s official. According to the August 2011 National Oceanic and Atmospheric Administration’s National Climatic Data Center, Texas had the hottest summer since they have been keeping records. And to compound the issue according to the website http://www.ncdc.noaa.gov/sotc/national/, “analysis of Texas statewide tree-ring records dating back to 1550 indicates that the summer 2011 drought in Texas is matched by only one summer (1789) in the 429-year tree-ring record, indicating that the summer 2011 drought appears to be unusual even in the context of the multi-century tree-ring record.”

All of the data that NOAA has accumulated seems to explain the record complaints of purple martin landlords, not only in Texas but in many States. Nestlings starving from drought, record heat causing nest fatalities and “jumpers”. Even Florida, Louisiana and South Carolina all experienced their warmest March-August recorded yet. Though Texas has not exceeded its record of the length of drought conditions, already the severity exceed those of the 1930′s “Dust Bowl”.
Unfortunately, nothing can be done about the weather, except perhaps, to wait it out. Taking the few steps we recommend to help your martins can perhaps help you to feel less helpless but even those steps can only help so much. Things like making sure your martin houses are well ventilated, using purple martin houses that utilize larger nest compartments and perhaps installing a misting system, are the only things that can help. So until next year, pray for more accommodating weather.
