Banded Doves

What a decade of data has shown

This month, dove hunters will be partaking in one of the most active wing-shooting seasons of the year. At about the same time, dove biologists will be closing out the busiest dove monitoring project in the United States: six weeks of nation-wide dove banding.

The dove hunter and the dove bander each play a crucial role in the largest dove data collection effort in the country: the annual capture, banding and recovery of more than 46,000 wild mourning doves in the U.S.

Dove Banding

Dove banding occurs each year in Pennsylvania from early July through mid-August. In more than 20 counties, Game Commission personnel begin spreading seed at trap sites in mid-June. In late June, wire cages appear near the bait piles as the seed continues to appear.

In early July, eager doves find that the wire contraptions are now blocking access to the free food, but as luck would have it, there are convenient tunnels leading to the delicious seed. Once inside the trap, birds continue to feed contentedly. Imagine a dove’s surprise then, when a human rushes up, pops the bird into a holding bag, places an aluminum band on its right leg, and quickly releases it.

Why all the fuss? doveband

The national banding program gathers data that is critically important to the National Dove Harvest Management Strategy. Setting seasons and bag limits requires a detailed understanding of key population factors including: 1) the annual survival of adult and juvenile doves; 2) the annual recruitment of young doves into the fall population, and; 3) the proportion of adult and juvenile doves that are harvested each year. None of these estimates would be possible without a comprehensive and sustained banding effort among federal and state wildlife agencies.

Dove Hunter Reports

All of the work required to band these 46,000 doves each year would be meaningless without dove hunters. When a successful hunter harvests a banded dove, he or she reports the band number and harvest location of the bird to the national Bird Banding Laboratory. Bands are engraved with a toll-free number (1-800-327-BAND) and a web address figure_how_recovered (002)( that make reporting simple and quick. Without this “encounter” or “recovery” information, the time and effort that goes into banding doves would be nearly worthless. Banding information is only meaningful when a banded bird is recovered at a later date. The hunter benefits, too, by receiving a report of when and where the dove was banded.

More than three quarters of all band returns come from dove hunters Randomly finding a dead banded dove on the landscape does occur, but these random encounters count for less than 10 percent of all recovered bands.

What have we learned?

You might be surprised at the important information gleaned from those shiny little rings on the ankle of a dove. For instance, we know that most doves banded in Pennsylvania are recovered in Pennsylvania. That tells managers that the majority of the annual Pennsylvania dove harvest is derived from Pennsylvania-breeding birds. In fact, the majority of Pennsylvania mourning doves are homebodies, traveling an average of 54 miles from their banding location to the point of recovery.recovery

By tracking the encounters of a banded cohort after banding, we can get a sense of the typical life span of wild mourning doves. For instance, in the bar graph, notice that the birds banded in 2006 (shown in deep purple) continue to be recovered in smaller and smaller proportions through 2011 Since we began intensive dove banding in Pennsylvania, we’ve learned that the typical life span (i.e. the average age of recovered birds) is 1.2 years.

For doves banded in Pennsylvania, the longest life span on record is that of a bird that was at least 8½ years old. This bird was banded as an adult near Reading in 2005, and was harvested by a hunter less than 2 miles away in December 2012.

Together, these pieces of information, provided through the collaboration of the U.S. Fish and Wildlife Service, state wildlife agencies, and dove hunters, provide a glimpse into the welfare of the mourning dove population. This data feeds directly into population models that determine the season length and daily bag limit of mourning doves from year to year. Without an ongoing dove banding effort, the setting of sustainable mourning dove seasons would be based on guesswork rather than science. By carefully calibrating dove harvest regulations with annual population dynamics, a sustainable dove season can be enjoyed by today’s dove hunters as well as future generations who follow us into the dove fields.

Controlled Burns and Wildlife

…or a bear, potentially a turkey, maybe even a grouse. Controlled burning improves wildlife habitat, and hunters should consider a new twist in their scouting this fall; find a burned area!

Fire has shaped Pennsylvania’s wildlife habitats for thousands of years with recurring fires that maintained oak forests, open woodlands, and grassy meadows – the perfect mix for turkeys, deer and other wildlife. But such habitats are actually threatened with fire removed from the equation. After 70 to 100 fire-free years, we’re seeing that formerly open habitats are now clogged with rank vegetation and oak forests are being replaced by fire-intolerant birch and maple; all to wildlife’s detriment. That’s why prescribed burning is an essential habitat management tool.

Controlled Burns Improve Hunting Opportunity

Who were the first prescribed burners in Pennsylvania? The Seneca, Susquehannock, Delaware and other tribes. Why did they burn? To improve hunting grounds and game populations.

Controlled burning improves wildlife habitat and hunting opportunity by:

  • Increasing soft mast production in shrubs like blueberry, huckleberry, and blackberry
  • Rejuvenating succulent browse plants preferred by deer and elk
  • Promoting oak habitats and their vitally important acorns
  • Maintaining grasses and broadleaf plants sought by brooding turkeys and grouse


Is Burning the Woods Safe?

Anatomy_Prescribed-Fire Controlled burns are much different than images we’re seeing in the news.Controlled burns are conducted under very specific weather and “fuel” conditions ensuring fires are low to moderate intensity (fuel refers to the dried leaves, grasses, and brush that are consumed in the fire). Additionally, controlled burns are normally repeated every 3 to 10 years, preventing fuels from building to dangerous levels. In this way, prescribed burns also reduce the risk of unplanned wild fires.

Controlled burns are conducted by highly trained crews with hundreds of hours of training and experience. Long before burn day, crews are planning operations and prepping fire lines to ensure safety, both for themselves and the public.

Is Wildlife Harmed?

BlueberryFawn2Controlled burn ignition patterns provide wildlife escape routes as the burn progresses. Burning during appropriate weather conditions ensures spread rates are slow and flame heights are low. From fawns to turtles, even the slowest wildlife can reach safety. Before the smoke clears animals are often seen returning to burned areas.

Because peak prescribed burning occurs in spring, we often hear concerns over impacts to ground nesting birds like turkeys and grouse. Prescribed burns may disrupt a few nests; however hens often re-nest and some nests in the burn area may not be harmed. Most importantly, burns occur on a relatively small percentage (less than 10%) of the landscape. In that light, the direct impacts are quite small and benefits far outweigh potential negatives.

Controlled burning is a valuable tool to improve habitat and hunting opportunity. It’s a great benefit to utilize this technique in Pennsylvania. To learn more about controlled burns visit the PA Prescribed Fire Council Facebook page and keep an eye out for upcoming controlled burn updates on the Game Commission’s website. Burned areas can be a haven for wildlife and finding a burned area could lead to great hunting this fall.
