Insects or Insecta (from Latin insectum) are pancrustacean hexapod invertebrates and the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within.–Wikipedia

Owing to their abilities to create large amounts of excrement and be an occasional disease vector to humans combined with crop and property damage, pigeons are largely considered a nuisance and an invasive species, with steps being taken in many municipalities to lower their numbers or completely eradicate them.–Wikipedia

Taxonomy and systematics
The osprey was one of the many species described by Carl Linnaeus in his 18th-century work, Systema Naturae, and named as Falco haliaeetus.[2] The genus, Pandion, is the sole member of the family Pandionidae, and used to contain only one species, the osprey (P. haliaetus). The genus Pandion was described by the French zoologist Marie Jules C├ęsar Savigny in 1809.[3][4]
Most taxonomic authorities consider the species cosmopolitan and conspecific. A few authorities split the osprey into two species, the western osprey and the eastern osprey.
The osprey differs in several respects from other diurnal birds of prey. Its toes are of equal length, its tarsi are reticulate, and its talons are rounded, rather than grooved. The osprey and owls are the only raptors whose outer toe is reversible, allowing them to grasp their prey with two toes in front and two behind. This is particularly helpful when they grab slippery fish.[5] It has always presented something of a riddle to taxonomists, but here it is treated as the sole living member of the family Pandionidae, and the family listed in its traditional place as part of the order Falconiformes.–Wikipedia
