A conifer cone, or in formal botanical usage a strobilus, pl.: strobili, is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads. They are usually woody and variously conic, cylindrical, ovoid, to globular, and have scales and bracts arranged around a central axis, but can be fleshy and berry-like.
The structure of the fossils also suggest that these birds may have been swifter than originally thought. [25] A skull from a smaller subspecies of this bird was also found recently. With this fossil, it was found that the internal structure of the beak is hollow and reinforced with thin-walled trabeculae.
Podocarpus (/ ˌ p oʊ d ə ˈ k ɑːr p ə s / [2]) is a genus of conifers, the most numerous and widely distributed of the podocarp family, the Podocarpaceae. Podocarpus species are evergreen shrubs or trees, usually from 1 to 25 m (3 to 82 ft) tall, known to reach 40 m (130 ft) at times.

Birds of the crow family, Corvidae, are the primary distributor of the conifer seeds. These birds are known to cache 32,000 pine seeds and transport the seeds as far as 12–22 km (7.5–13.7 mi) from the source. The birds store the seeds in the soil at depths of 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) under conditions which favor germination. [27]
Nightjars are medium-sized nocturnal or crepuscular birds in the family Caprimulgidae / ˌ k æ p r ɪ ˈ m ʌ l dʒ ɪ d iː / and order Caprimulgiformes, characterised by long wings, short legs, and very short bills. They are sometimes called bugeaters, [1] their primary source of food being insects. Some New World species are called nighthawks.
Males and young birds also have red markings on the neck or head. This species is found across the Palearctic including parts of North Africa. Across most of its range it is resident , but in the north some will migrate if the conifer cone crop fails.
The birds were once common and abounded on the Salisbury Plain. They had become rare by 1819 when a large male, surprised by a dog on Newmarket Heath, sold in Leadenhall Market for five guineas. [22] The last bustard in Britain died in approximately 1832, but the bird is being reintroduced through batches of chicks imported from Russia. [21]
