Cycads are regarded as the "Living Fossils" and belong to a specialized group of plants having ancient lineage possessing great signifi cance from the evolutionary point of view. During excavations, the cycad fossils located and accepted as related to the similar lineage as the present-day cycads have been known from the early Permian period, ca. 280-320 Myr ago. They had been popularly known as "Plant Dinosaur" and were generally known as the most dominant plant group in the Mesozoic period. The relict group of the seed plants was worldwide in their distribution and dominant in the plant world as the dinosaurs were then at the peak in the animal world. They were eaten by some herbivorous dinosaurs, such as Stegosaurs . During that period the plant group Bennettitales or cycadeoids was in abundance which had superfi cial resemblance with cycads but was more similar and closer to the angiosperms. The Jurassic period is generally called as the "Age of Cycads" because they were very common at that time. In fact the cycads represent the basal living lineage of the presentday seed-bearing angiosperms.The taxonomic isolation and extreme antiquity of cycads have attributed them intrinsic interest and conservational importance which is disproportionate to the paucity of members because of their limited and disjunct distribution. The cycads are dioecious and very slow-growing plants; as a result they are getting extremely rare in the natural habitat. Due to their rarity, very attractive foliage and beautiful cones, cycads are considered as the prized collections in private and the public gardens leading to over exploitation from natural habitats and illegal trade in the international market. Therefore, international trade and the movement of A.

“…Ali (2009) observed the nest site selection and prey delivery patterns to nestlings by the Baya Weaver in Tamil Nadu, India and by using Analysis of Variance (ANOVA) they inferred that tree height, total number of leaves, number of leaves in the middle area of tree, and number of dried leaves has significant variation between nesting and non-nesting trees and the female Baya Weaver delivered different prey items to their nestlings such as grasshoppers, caterpillars, unknown items, etc. Raju (2009) emphasizes the nesting behaviour of the Baya Weaver in the Eastern Peninsular region of India on hills distributed from Chennai North to Bhubaneshwar and concluded that the Baya Weaver bird, Ploceus philippinus uses the well-developed leaves of Cycus spaerica and Dendrocalamus strictus for their nest building. Narwade et al (2010) conducted a survey on birds of Osmanabad in the Marathwada region and they find that the area still provides some potential habitats for the declining population of the threatened birds.…”

Birds are one of the important indicators of the state of the environment and changes in bird populations are often the first indication of environmental problems. Hence, the health of these birds is very important. Working on nesting material and nesting behaviour of different birds, we can find new approaches for the conservation of the different bird species. Another vital aspect of birds' health is the CaCO3 proportion in their eggshell, which is a good indicator of a healthy environment. Hence, by working on the CaCO3 content of eggshells of the birds of different areas, we can monitor different areas. This will help in creating a protocol to identify proper methods to assess the health of the ecosystem in which we live. Furthermore, we examine the potential links between nesting behaviour and the variation in calcium carbonate content, investigating how nest site selection, nest lining, and nest architecture may influence the deposition of calcium in the eggshell matrix. Additionally, this review discusses the implications of altered nesting behaviour and shifts in calcium carbonate availability due to anthropogenic influences such as habitat destruction, climate change, and pollution. Understanding these potential impacts is crucial for assessing the reproductive success and population dynamics of various bird species in the face of ongoing environmental changes. This study provides valuable insights into the adaptive significance of nesting behaviour and the dynamic nature of eggshell composition across different avian taxa. This knowledge contributes to the conservation efforts and management strategies aimed at preserving the reproductive success and overall health of avian populations in the midst of a changing world.

“…The nest of P. philippinus is pendulous, suspended to leaf tips, monostoried, stalked, and retort shaped with a central nesting chamber and long vertical tube that leads to a side entrance to the chamber (Venkataramani 1981). Wood (1926) mentioned that weaver birds instead of building a nest once or twice in a year they reuse the old nest by repairing it, Raju (2009) reported that male Weaver birds constructed a new nest because of old ones may fall along with the leaf during an annual leaf fall. The Weaver bird rarely constructs a stalk-less nest because such nests are hardly ever excepted by the female weaver bird (Sharma 1995).…”

“…The Weaver bird rarely constructs a stalk-less nest because such nests are hardly ever excepted by the female weaver bird (Sharma 1995). There are five stages in the construction of a nest initial attachment, roof and egg/brood chamber, antechamber, entrance, and entrance tube (Raju 2009). Nest building was initiated by winding strands of grass around a selected twig until J TT firm support was secured.…”

“…India is home to four Ploceus (Lack 1954(Lack , 1968Grewal et al 2016;Grimmett et al 2016): Blackbreasted Weaver P. benghalensis, Streaked Weaver P. manyar, Finn's Weaver P. megarhynchus, and Baya Weaver P. philippinus. There are many works on nesting and population ecology (Quader 2005(Quader , 2006Borges et al 2002;Raju 2009;Pandian & Ahimas 2018;Kumar et al 2018;Pandian 2022), but a combined review has not been prepared to date. This review provides baseline information about the nesting, mating, and population ecology, in addition to conservation status.…”

A review of Baya Weaver Ploceus philippinus (Linnaeus, 1766) (Aves: Passeriformes: Ploceidae): ecological and conservation status

Baya Weaver Ploceus philippinus is a highly social and gregarious bird of the family Ploceidae that has been recently listed as ‘Least Concern’ by the IUCN Red List of Threatened Species. In India, four species of genus Ploceus are reported to date. This study focused on the appearance, distribution, diet specificity, nesting ecology, mating behaviour, and physiological responses to seasonal changes of P. philippinus. Populations have declined due to poor cultivation practices by farmers, rapid urbanization, and industrialization that have resulted in habitat loss. Weaver birds also face threats due to natural predators such as birds, and from insect damage to chicks, eggs, and nests.
