Songbirds
Vocalization, Animal
Sounds used in animal communication.
Finches
Common name for small PASSERIFORMES in the family Fringillidae. They have a short stout bill (BEAK) adapted for crushing SEEDS. Some species of Old World finches are called CANARIES.
Starlings
The family Sturnidae, in the order PASSERIFORMES. The starling family also includes mynahs and oxpeckers.
High Vocal Center
Nucleus in the NEOSTRIATUM of bird brains that sends signals for song production and receives auditory input. In some adult SONGBIRDS, research has shown that the size of this nucleus changes seasonally and that it exhibits neurogenesis.
Sparrows
The family Passeridae comprised of small, mainly brown and grey seed-eating birds with conical bills.
Canaries
Any of several Old World finches of the genus Serinus.
Animal Migration
Sound Spectrography
Prosencephalon
The anterior of the three primitive cerebral vesicles of the embryonic brain arising from the NEURAL TUBE. It subdivides to form DIENCEPHALON and TELENCEPHALON. (Stedmans Medical Dictionary, 27th ed)
Animal Communication
Auditory Pathways
NEURAL PATHWAYS and connections within the CENTRAL NERVOUS SYSTEM, beginning at the hair cells of the ORGAN OF CORTI, continuing along the eighth cranial nerve, and terminating at the AUDITORY CORTEX.
Birds
Warm-blooded VERTEBRATES possessing FEATHERS and belonging to the class Aves.
Auditory Perception
Passeriformes
A widely distributed order of perching BIRDS, including more than half of all bird species.
Learning
Basal Ganglia
Large subcortical nuclear masses derived from the telencephalon and located in the basal regions of the cerebral hemispheres.
Acoustic Stimulation
Use of sound to elicit a response in the nervous system.
Beak
In some animals, the jaws together with their horny covering. The beak usually refers to the bill of birds in which the whole varies greatly in form according of the food and habits of the bird. While the beak refers most commonly to birds, the anatomical counterpart is found also in the turtle, squid, and octopus. (From Webster, 3d ed & Storer, et al., General Zoology, 6th ed, p491, 755)
Territoriality
Telencephalon
The anterior subdivision of the embryonic PROSENCEPHALON or the corresponding part of the adult prosencephalon that includes the cerebrum and associated structures.
Air Sacs
Thin-walled sacs or spaces which function as a part of the respiratory system in birds, fishes, insects, and mammals.
Seasons
Acoustics
The branch of physics that deals with sound and sound waves. In medicine it is often applied in procedures in speech and hearing studies. With regard to the environment, it refers to the characteristics of a room, auditorium, theatre, building, etc. that determines the audibility or fidelity of sounds in it. (From Random House Unabridged Dictionary, 2d ed)

Sound
Brain
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
Molting
Periodic casting off FEATHERS; HAIR; or cuticle. Molting is a process of sloughing or desquamation, especially the shedding of an outer covering and the development of a new one. This phenomenon permits growth in ARTHROPODS, skin renewal in AMPHIBIANS and REPTILES, and the shedding of winter coats in BIRDS and MAMMALS.
Nesting Behavior
Photoperiod
Parakeets
Common name for one of five species of small PARROTS, containing long tails.
Auditory Cortex
Ischnocera
A suborder of chewing lice, in the order PHTHIRAPTERA, that are parasites of birds and mammals.

Crows
Common name for the largest birds in the order PASSERIFORMES, family Corvidae. These omnivorous black birds comprise most of the species in the genus Corvus, along with ravens and jackdaws (which are often also referred to as crows).
Vasotocin
A nonapeptide that contains the ring of OXYTOCIN and the side chain of ARG-VASOPRESSIN with the latter determining the specific recognition of hormone receptors. Vasotocin is the non-mammalian vasopressin-like hormone or antidiuretic hormone regulating water and salt metabolism.
North America
While there isn't a specific medical definition for "North America," I can provide a geographical definition that is often used in public health and medical contexts: North America is the third largest continent by area, encompassing 23 independent states, including the United States, Canada, and Mexico, which are home to diverse populations, cultures, and ecosystems, and share common health-related challenges such as obesity, diabetes, and healthcare access disparities.
