What is the Pennsylvania Migration Count?
The Pennsylvania Migration Count (PAMC) was established to gather annual data on migratory bird populations, and to help answer some fundamental questions regarding their distribution throughout Pennsylvania. PAMC is an annual one-day snapshot of bird populations within our state attempting to answer which species are present, where are they and how many there are? Detecting the changes in population will help give us an early warning of possible declines and it is hoped that steps can be taken toward assisting their future survival.
How does it work?
The Pennsylvania Migration Count takes place each spring on the second Saturday in May, in conjunction with International Migratory Bird Day. PAMC is similar to the Christmas Bird Count (CBC). The difference is that PAMC takes place on a countywide basis, rather than within the confines of a CBC circle. The rules are simple: spend some time in the field counting all birds encountered in a specified area, and keep track of miles traveled and time spent counting. Participants are free to roam their favorite county birding locales at any time during the 24 hour period, starting at 12:01am, counting every bird that they find. Totals are passed along to county compilers, who, in turn, report to the state compiler. The state compiler maintains the PAMC data, and an annual report is published in Pennsylvania Birds, the journal of the Pennsylvania Society for Ornithology (PSO).*When did it start? The Pennsylvania Migration Count originated as part of the continent-wide North American Migration Count (NAMC) in 1992, when there were 141 observers in 10 Pennsylvania counties. The count grew steadily in popularity in PA over the years, and was renamed PAMC in 2003, reflective of the fact that the national count was struggling everywhere but in Pennsylvania. Last year 903 observers from 53 counties participated in the PAMC. They counted 120 birds of 238 different species in over 2932 field hours. This year there are already more counties committed while we are always looking for more people to help. This year has us up to 59 counties committed out of the 67 in the state.
How can you help?
Birders of all skill levels can help out with the count. Beginning at midnight with the songs of the Whip-poor-wills and the hooting of the Great Horned Owls, the PAMC is a great way to spend time outside. Whether you tally birds in your backyard, at your feeders, the local little league ball field, along the river, on a lake, at your camp or spend time hiking through a state park, your observations count. Forms and information for PAMC participation are available from your county compiler, or go online at www.pabirds.org/PAMC/Index.html Data can be submitted via e-mail or post. If participating or for more information, please contact the county compiler first, to avoid duplicate submissions from the same area. If no compiler, contact PSO@PABIRDS.ORG for submission or assistance. You are always welcome to enter your own information on www.ebird.org, a free & public site, for submissions by the general public. This contributes valuable information that is used to track trends of birding population and distribution. This site allows you to keep track of your own sightings where ever you go and see what else is being seen in your area.
