The effects of tracheal coiling on the vocalizations of cranes (Aves; Gruidae)

Journal of Comparative Physiology A, 1987
It is generally supposed that the elongated, often coiled tracheae of many species of birds are adaptations for the production of loud, penetrating calls. A corollary supposition is that the acoustic effects are produced by the resonant properties of the elongated tube, with the birds being analogized to a wind instrument.

[Plumage structure and skin weight in nestlings of cranes (Gruidae, Gruiformes)].

Izvestiia Akademii nauk. Seriia biologicheskaia, 2008
A decrease in the down density and integument relative weight has been demonstrated in the ontogeny of nestlings. Coupled with the differentiation of the down cover (several generations of the down and down plumages with a typical heterochrony), this provides for the development of a multilayer thermal insulation cover evenly distributed over the ...

Cloning and characterization of a tandemly repeated DNA sequence in the crane family (Gruidae)

Genome, 1989
A tandemly repeated DNA sequence possessing a unique PstI site has been characterized in several species of the crane family. The "Pst family" comprises at least 8800 monomer units 187 base pairs (bp) in length and constitutes 0.14% of the genome of the sarus crane (Grus antigone).

Respiratory responses to acute heat stress in cranes (Gruidae): The effects of tracheal coiling

Respiration Physiology, 1985
Some species of cranes have extensive coiling of their trachea that substantially increases their anatomical dead space. We subjected individuals of four species of cranes (Anthropoides virgo, Balearica regulorum, Grus grus and Grus japonensis) to acute heat stress to investigate the effectiveness of this trait as a thermoregulatory adaptation.

Herpesvirus-Hepatitis bei Kranichen (Aves: Gruidae) I. Pathomorphologische Befunde

Zentralblatt für Veterinärmedizin Reihe B, 2010
Zusammenfassung Bei 6 Kranichen (Balearica pavonina L. und Anthropoides virgo L.) wurde ein einheitliches pathomorphologisches Krankheitsbild nachgewiesen, welches vor allem durch miliare und submiliare Nekroseherde in Leber, Milz und Digestionstrakt, zum Teil auch in Knochenmark, Nieren und Schilddrusen gekennzeichnet ist.

Anatomy of the middle ear of the japanese crane Grus japonensis (gruidae: Aves)

Journal of Morphology, 2003
AbstractComparative anatomical studies of the avian middle ear provide structural data from which functional models can be derived. Subsequent phylogenetic analyses may reveal the phylogenetic history of taxon and the evolution of the functional model of the middle ear. We studied serial sections of a nestling of Grus japonensis.
