Tree swallows have moved into one of the boxes in our Old Field and are busily building a nest inside.
Swallows get busy with staking a claim to a nest box and beginning the process of nest-building soon after arriving back in our area. By early July they have left the garden. Once the young have fledged they're off, no lingering as many other species do. They give real meaning to the phrase "Post-breeding dispersal"! Swallows soon congregate with other swallows and by mid-summer you can see them lining up along hydro wires, or fence posts, swooping after insects, getting ready for the journey south.
