Night Migratory Songbirds Exhibit Metabolic Ability to Support High Aerobic Capacity during Migration
Laboratory studyOther animals
- Design
- Laboratory study
- Subjects
- Male redheaded buntings (migratory songbirds) in non-migrating and photostimulated migrating states; numbers not stated in the abstract
- Dose used in the study
- No palmitoylethanolamide was given; serum levels were measured
- Duration
- Not stated in the abstract
- What was measured
- Serum metabolites by gas chromatography-mass spectrometry across the day in non-migrating and migrating birds, alongside behaviour and physiology.
What the authors reported
This laboratory study found:
- Daytime feeding went with higher fatty acids and protein catabolites, while night-time short-chain fatty acids indicated lipolysis.
- Migrating birds had higher circulating fatty acids and aerobic catabolism, and palmitoylethanolamide levels were raised throughout the day.
- This is described as the first record of daily palmitoylethanolamide changes in a migrating bird.
- Pyridoxal phosphate was also higher during migration.
Limits of this study
An observational study of serum chemistry in birds; it cannot show effect in people or animals treated in practice. No PEA was administered. The authors declare no competing financial interest.
