A few pine siskin dropped in for a visit yesterday.
This is just a few of the siskin that came to the yard. The pond was a popular place.
Spinus pinus
Pine Siskins can temporarily store seeds totaling as much as 10% of their body mass in a part of their esophagus called the crop. The energy in that amount of food could get them through 5–6 nighttime hours of subzero temperatures.
