From Psalm 84.3 (ESV):
Even the sparrow finds a home, and the swallow a nest for herself, where she may lay her young, at your altars, O LORD of hosts, my King and my God.
Banquo speaking before Macbeth’s castle:
This guest of summer,
The temple-haunting martlet, does approve
By his loved mansionry that the heaven’s breath
Smells wooingly here. No jutty, frieze,
Buttress, nor coign of vantage, but this bird
Hath made his pendant bed and procreant cradle;
Where they most breed and haunt, I have observed
The air is delicate.
