MAPS Visit 1 – Maplewood Bog (2010)

Wood Thrush recaptured (banded on July 25, 2009)

The inclemency of late has made scheduling our first round of MAPS visits a challenge. Our first morning at Maplewood Bog (MABO) in 2010 began with some trepidation over the forecast of 40% chance of showers. It wasn’t raining when we arrived but the vegetation was dripping wet, which made net setup feel like a 5 a.m swim through the woods and meadows. There were only a few brief periods of drizzle during the morning until the final round when a torrential downpour occurred. We were able to get a full six hours of coverage but the final round was more than a little uncomfortable!

Fortunately, despite the weather, the birds were numerous and active. The highlight of the morning was the recapture of eight birds banded last summer at the site, which included three Veery and two Wood Thrush. These two are dominant species at MABO and both migrate to and from Latin America on an annual basis. The Veerys that we recaptured on this day may winter as far south as the Amazon basin, some 7,000 km south of MABO! This is one of the great marvels and joys of participating in the MAPS program, it vividly connects you to the remarkable life cycles of individual birds and bird communities. For example, we know this Veery (2431-64408) was an ASY male on June 14, 2009 with a wing length of 101mm and a weight of 30.8g. We also knew the age and wear of its feather tracts, breeding condition, its territory location and the onset of its prebasic moult. We re-caught this word traveler on June 10, 2010. He was found in the same net as last year and is likely paired with 2431-64405 – a female that we suspect reared these young with a different male in June, 2009!

We were too drenched and busy to take many photos of birds during the visit but we did capture a respectable 21 birds of 12 species. Cerulean Warbler and Black-throated Blue Warbler were notables detected but not captured. A full summary of the capture results is presented below.

  1. WOW! That got our attention. It’s remarkable that these birds return to the same area, let alone the same site and that you get them in the nets.

    Better luck next time with the getting wet part.

  2. […] Our first visit to Maplewood Bog in 2010 was a little bit unpleasant due to the wet and ominous weather we endured. We were pleased to give MABO a proper go for visit 2 with clear, warm and dry conditions. The birds were much more active, although Seabrooke and I agree that breeding density seems lower for most species this year. This isn’t too surprising as our 2009 results suggested low productivity for last summer and numbers were way down at most migration monitoring stations this past spring. Visit 2 was all about the Red-eyed Vireo! A total of seven were captured, which included several returns from 2009. We also recaptured two Northern Waterthrushes, which have successfully returned to MABO from their winter haunts in either the Caribbean or Central America. […]
