Texas' tens of millions of resident doves have had a good, maybe even great, year, with the birds enjoying above-average nesting success thanks to much of the state seeing timely rains and moderate temperatures during spring and summer. For Texas' 300,000 or so dove hunters, that abundance of birds - as many as 50 million mourning, white-winged and Eurasian collared doves, the three dove species most often taken by the state's wingshooters - holds considerable promise of an equally good, and maybe even great, dove hunting season, which opens Monday in the North and Central zones.
