This short report describes how we tested the reliability of a proposed bill character for separating Marsh Tits and Willow Tits of several European races in the hand. Pooling all samples (395 birds), the probability of accurately identifying an unknown bird as a Marsh Tit or a Willow Tit, based only on the presence or absence of pale marks on both sides of the upper mandible, was 98.0%. The bill criterion was therefore validated as a highly reliable method of separating Marsh Tits and… 
Separating British Marsh Tits Poecile palustris and Willow Tits P. montana using a new feature trialled in an online survey
TLDR
The pattern of the greater coverts is recommended as an additional, complementary criterion for separating Marsh Tits from Willow Tits, based on differences in the pattern of colour contrast on the greater covert feathers.
Sulla presenza della Cincia alpestre Poecile montanus in Appennino centrale
TLDR
It is hypothesized that all Willow Tit recorded observations relate instead to Marsh Tit, concluding that no Willow Tit populations were ever recorded in the Central Apennines.
Separation of Willow Tit and Marsh Tit in Britain: a review
TLDR
Recommendations are made for the key criteria to be used for field, photographic and in-hand identification, with a primary focus on voice, bill marks, cheek pattern, plus wing and tail measurements and the presence or absence of a clear wing panel.
Comparative biometrics of British Marsh Tits Poecile palustris and Willow Tits P. montana
TLDR
This work presents biometrics for a large sample of Marsh Tits of known age and sex, and new data for Willow Tits, which act as reliable reference material, and discusses issues of measurement accuracy and consistency in the collection and analysis of biometric data.
Calls of nestling and fledgling Marsh Tits Poecile palustris
ABSTRACT Many knowledge gaps exist in the descriptions of the vocal repertoires of most bird species, and particularly for the calls of nestlings and fledglings. This short descriptive study presents

Separation of marsh tits parus palustris and willow tits parus montanus
TLDR
Only tail ‘shape’ and the difference in length between T6 and T3 proved reliable and should be given the most weight, with others used as supporting features, when separating birds in the hand.
Ageing and sexing Marsh Tits Parus palustris
The presence or absence of juvenile greater coverts and the shape of tail feathers were not found to be reliable ageing characters in a population of Marsh Tits in which juveniles usually replaced
Possible roles of habitat, competition and avian nest predation in the decline of the Willow Tit Parus montanus in Britain
TLDR
The evidence of this study suggests that the major cause of the Willow Tit's decline in Britain is habitat degradation, especially in woodland.
Avian nest predation, competition and the decline of British Marsh Tits Parus palustris
TLDR
Data from long-term schemes monitoring abundance and breeding performance were used to investigate the patterns and causes of decline of the Marsh Tit Parus palustris in Britain, finding no evidence that increases in the numbers of either group have had a deleterious effect on the species.
