शकुनानि
कोटरे वासमानश्च महानर्थकरो भवेत् ।न शुभंस्तूषरे काकः पङ्काङ्कः स तु शस्यते ॥ १२ ॥
In the full Agni Purana this is chapter 232, verse 12.
Living in a hollow, it may bring great harm. A crow on salty ground is not good. One marked with mud is praised.
Simple meaning: A crow in a tree hollow can bring great harm. On salty ground it is not good. A muddy one is good.
अमेध्यपूर्णवदनः काकः सर्वार्थसाधकः ।
A crow with filth in its beak brings success. Other birds read like the crow.
स्कन्धावारापसव्यस्थाः श्वानो विप्रविनाशकाः ।
Dogs on the right of a camp harm brahmins. A dog barking at a shrine or gate can mean a ruler's death.
अन्तर्गृहे गृहेशस्य मरणाय भवेद्भषन् ।
A dog barking inside the house means death for the owner. Sniffing someone's left side brings his aim.
