Passerines (members of the order Passeriformes such as finches, chickadees, jays, and warblers) are predominantly small birds characterized by relatively intense metabolic rates. Members of this group breeding at middle or high latitudes may either evade winter cold by migration or enhance their resistance to it by acclimatization. We review the energetic consequences associated with these two modes of response. Despite their apparent dissimilarity, migration and winter acclimatization both depend on substantial aerobic endurance, and both involve extensive power outputs by the flight muscles in locomotion or shivering. Such power outputs entail extensive deposition and catabolism of fat. Information available on these processes and their control in passerine birds is discussed. Knowledge of them is still in a formative stage, but it is already clear that aerobic capacity of passerines is stable at a high level throughout the year. However, changes are observed in the activity of certain enzymes involved in the catabolism of fats and carbohydrates. Full interpretation of these findings must await additional research. Nevertheless it is evident that the complex processes of migration and winter acclimatization are intimately linked with the metabolic properties of the highly aerobic skeletal muscle contained within the flight apparatus of passerines.

Lay Summary • There is equivocal support for direct associations between maternal quality and deposition of protoporphyrin pigmentation (dark spots and blotches) in avian eggshells. • Research on protoporphyrin eggshell pigmentation has primarily focused on a single avian order (Passeriformes). • We examined associations of protoporphyrin-based eggshell pigmentation with female phenotypic and genetic traits in a non-passerine species, the Eurasian Coot. • Deposition of protoporphyrin in eggshells (total number per area of egg spots) positively correlated with female condition and expression of a putative bare-part ornament (frontal shield), while it was negatively associated with the level of physiological stress. • Protoporphyrin-based eggshell pigmentation acts as a reliable signal of female phenotypic (but not genetic) traits in the Eurasian Coot. • Signaling properties of protoporphyrin-based egg coloration are likely to largely differ between different evolutionary lineages of birds.

The identities of chlamydial strains, which can infect a given host, are important to know for disease prognosis, disease control, and epidemiology. The microimmunofluorescence test (MIFT) was used with a panel of 14 serovar-specific monoclonal antibodies (MAbs) to serotype 150 chlamydial isolates from domestic and wild birds. The isolates were obtained from birds submitted to diagnostic laboratories or during investigation of outbreaks. The 150 US isolates included 96 from the order Psittaciformes, 14 isolates from the order Columbiformes, 2 from the order Passeriformes, 16 from the order Galliformes, 12 from the order Struthioniformes, and 3 from the order Falconiformes. A total of 93, or 97%, of the Psittaciformes isolates were of serovar A; 11, or 79%, of the Columbiformes isolates were of serovar B; 64% of the Galliformes isolates were of serovar D, and all the Struthioniformes isolates were of serovar E. The 3 Falconiformes isolates did not react with any of the MAbs to the avian and mammalian isolates and are presumed to represent a new strain. The results show that specific chlamydial strains are usually associated with certain types of birds and that some serovars may be unusually virulent for certain species of birds. The MIFT using serovar-specific MAbs provides a rapid method to serotype new isolates, making it a useful system for epidemiological studies.
