Subject: [obol] Hybrid zone
There are zero titmice to the east of Adel and zero to the north. Why would this spot generate hybrids? There is a large titmousefree zone west of the Warner Range.  I fully understand the pitfall of basing an ID on geography alone. But the isolation of the Adel population makes trying to turn it into a hybrid zone spurious at best.Sent from my Verizon, Samsung Galaxy smartphone
