Matsya Purana — Description of Atri’s Hermitage: Sacred Grove Planning
तथा कादम्बकान्हंसान् कोयष्टीन् खञ्जरीटकान् कुररान्कालकूटांश्च खट्वाङ्गान् लुब्धकांस् तथा //
tathā kādambakānhaṃsān koyaṣṭīn khañjarīṭakān kurarānkālakūṭāṃśca khaṭvāṅgān lubdhakāṃs tathā //
Likewise, one should recognize the kādambaka-ducks, the swans, the koyaṣṭi birds, the khañjarīṭaka (wagtails), the kurara (ospreys), the dark kālakūṭa birds, as well as the khaṭvāṅga birds, and also those called “lubdhaka” (bearing the name “hunter”).
This verse does not describe Pralaya directly; it functions as a taxonomic/ritual-ecological listing of birds, a type of catalog often used in Puranas to frame dharmic order in the living world rather than cosmic dissolution.
By identifying classes of birds, the text supports dharmic regulation—kings and householders were expected to understand living beings relevant to ritual purity, omens, and the management of lands/waters (especially waterfowl and fish-eating birds) in a regulated, non-chaotic social order.
Such bird-lists commonly serve Vastu/ritual ecology: the presence, calls, or nesting of specific birds could be read as indicators for site selection, auspiciousness, and environmental suitability around temples, tanks, and settlements, even when the verse itself is simply enumerative.
