The wind was much calmer this morning but unfortunately it did not translate into that many more birds. We only banded 6 new birds and had 17 recaptures of 7 different species. The King Tides this week have been very large and have been running above the predicted heights resulting in a flooded banding station. At the peak of high tide, we are wading through up to 2 feet of water along our trails in some areas. This makes for great exercise but also very wet feet. Tomorrow will be the highest of the King Tides with a predicted height of 7.2 feet at 8:00am. After that, the tides will begin to taper off again to more reasonable levels. However, the water that was brought into the banding station will remain for a couple weeks until is evaporates or soaks into the saturated soil.
An interesting note on our recaptures from today...12 out of the 17 were from birds that were banded in a previous season.

The biggest surprise of the day was Black Rail carcass that was found sitting in one of our nets. Now this bird was not predated in our net but carried there by a raptor (probably a Cooper's Hawk). The assumed Cooper's Hawk most likely dropped the Black Rail after it flew into the net. The Coop was able to get out but left its breakfast behind. Because of the the huge tides, rails and other marsh birds are more vulnerable to predation as their habitat is flooded and they are forced to seek shelter in unfamiliar or less sheltered places.

LITTLE BEAR
Out at Little Bear the wind was fairly calm. Unfortunately, we had a low number of birds with 11 new birds and 14 recaptures with a total of 11 species. Our three highest species of the day were Gray Catbirds (1 new, 5 recaptures) , Yellow-rumped Warblers (2 new, 3 recaptures) and Ruby-crowned Kinglets (4 new, 1 recapture). We also had a lone Prairie Warbler, a bird we haven't seen in a few weeks. It is amazing that small birds such as Prairie Warbler and kinglets are able to cope with these cool temperatures.
