Captain Sam's
Unfortunately today was yet another slow day out at Captain Sam's. The majority of our captures today were recaptures from this season and a few recaptures from last year. Some of which landed in the nets more than once. One interesting recapture from today was an Adult Male Yellow-rumped Warbler that was banded last year on Nov. 15th. This bird was initially captured and banded as a Hatch-year male with a wing length of 72mm. Today when we recaptured him we measured his wing length to be 75mm. In general, birds with shorter and rounder wings are typically built for agility and maneuverability. While birds with longer pointed wings are better equipped for long fast flights at minimal energy expenditure. Some studies suggest that younger birds may feel more selective pressures to have shorter and more rounded wings in order to better avoid predators (http://aukjournal.org/doi/full/10.1525/cond.2008.8396). Its always interesting to recapture birds from previous years and learn as much as possible from each one!

Little Bear
Today was a fairly uneventful day out at Little Bear, with 40 newly banded birds and 10 recaptures of 12 species. We were missing some of the thrushes and sparrows that had been coming through in the past few days; instead seeing good numbers of Yellow-rumped Warblers and Gray Catbirds, among many of our regular species.
