We have swallows nesting under the eaves of our house on three sides. They've been here for years.
Psalm 84:1-4 KJV
How amiable are thy tabernacles, O Lord of hosts! [2] My soul longeth, yea, even fainteth for the courts of the Lord : my heart and my flesh crieth out for the living God. [3] Yea, the sparrow hath found an house, and the swallow a nest for herself, where she may lay her young, even thine altars, O Lord of hosts, my King, and my God. [4] Blessed are they that dwell in thy house: they will be still praising thee. Selah.
