Kāmikāgama while explaining the types of Pañjaras, explains the following pañjaras.
सार्धपञ्जरमन्यत्स्यात्तृतीयं पञ्जरं मतम् १३२
निर्यूहपञ्जरं पश्चात्पञ्चमं लम्बनासिकम्
सिंहश्रोत्रं तु षष्ठं स्यात्खण्डनिर्यूहकं ततः १३३
The Pañjaras are classified as Siṃha Pañjara, Sārdha Pañjara, Pañjara, Nirvyūha Pañjara, Lambanāsika, Siṃha śrotra, Khaṇḍa nirvyūhaka and Jhaṣa Pañjara.
The definition of these Pañjaras are given then. Apart from these eight another one is explained as Kapota Pañjara.
पञ्जाराकृतिसंयुक्तं कपोतात्तु विनिर्गतम् १५२
यथाशोभं यथायुक्ति तथा शक्तिध्वजान्वितम्
कपोतपञ्जरं ह्येतत्प्रासादे सार्वदेशिके १५३
The structure which has the definition of Pañjara and extended upto the Kapota Pāli with śakti dhvaja and with ornaments is termed as Kapota Pañjara. This can be used in Sāravdeśika vimānas.
Such a Pañjara is seen in the Pādavarga of Ravikulamāṇikyeśvara built by āḹvār Parāntakaṉ Kundavai, the elder sister of Rājarāja I and finished the same during the 21st regnal year of the later i.e 1006 CE.
The Pañjara is of ṣaḍvarga type. It has a Padmapuṣkala adhiṣṭhāna and a Vedikā. Further it has Rudrakānta type of Nakulapādas based on śuṅḍu pādas. Above the usual ornaments, a Potikā and a Kapota structure with nāsīs are carved. Above the Kapota a Vyāla mālā followed by a vedikā is projected. The grīvā portion contains a figure (warrior and a monkey) is carved. Nandi is also seen in another Kapota Pañjara. Above that a Mahānāsikā with simḥa vaktra is well carved. The Mukhapaṭṭis are well decorated with vallīmaṇḍalas and the gāḍha portion has figure of kṣudra vimāna. One Kapota Pañjara has figure of Vināyaka on Mūṣika.
Such Kapota Pañjara is not seen in other temples. Kāśyapa śilpaśāstra too mentions Kapota Pañjara while explaining the Drāviḍa vimāna.
