“…Overall mean frequency of individuals is lower than reported for central Spanish localities [88] which reflect strong differences among Iberian populations and the use of different methodological approaches, but flock numbers seem comparable to the observations found in winter in Poland [89]. This study confirms the not significant differences in body condition among those forming small groups (colonial) and solitaries [19].…”

“…This variability in dispersal occurs in other marshland passerines [13,15] and illustrates the importance of not manage earlier successional stages of reed to improve passerines movements. It is found that, on average, overnight weight loss was high and is lower than reported in other Tits of related size and mass [89]. Such loss weight might aid to explain why Bearded Reedling's movements are nocturnal from nesting to roosting areas starting during sunset and stopping on arriving at the roosts, probably associated to the advancement of high flying flights peaks at the sunrise pointed by [4,21].…”

Abstract:The behavioural ecology of the Bearded Reedling Panurus biarmicus in wild using data available from mistnetting has received little attention. One of such aspects is to evaluate if flock composition and structure vary among reed successional stages and facilities dispersal among near wetlands in small and semi-isolated populations by analysing mistnetting capture events. This study shows that mist-netting events comprised catches of solitary birds or small groups in samples from small to moderate size. Overall mean frequency of each flock result in a population of low aggregation at low densities and being lower than reported from bigger central Spanish populations. A majority of birds of these flocks are "transients", characterized by have shorter wing lengths and smaller body masses compared to "residents", which attain higher body masses and longer wing lengths. Residents have the ability to settle in unmanaged sparse habitats in the periphery of the wetlands and the possibility to undertake longer flights outside wetlands is greater due to a higher condition and performance. Since a high overnight mass loss of birds has been verified in this study, I hypothesize that Bearded Reedlings move in short-times elapsed from sunset (before arriving at the roosts) to sunrise, so earlier surveys carried out in wetlands might give inadequate results to monitoring Bearded Reedling's populations, demanding alternative methods to survey them properly. Due to the occurrence of such residents, the importance of saltmarshes with reed sparse-patches in the periphery of wetlands results in a key factor for the dispersal of this species.

“…One important factor that can influence the temporal dynamics of Bearded Reedling populations is weather conditions, particularly during the winter months. Harsh winters with prolonged periods of snow and ice cover can lead to reduced foraging opportunities, which can result in dramatically reduced survival and breeding success (Bibby 1983, Wawrzyniak & Sohns 1986, Cramp & Perrins 1994, Wilson & Peach 2006, but see (Surmacki & Stępniewski 2007). These adverse conditions can sometimes lead to local extinctions (extirpation), particularly in areas where Bearded Reedlings occur at the edge of their range (Wawrzyniak & Sohns 1986).…”

Bearded Reedling (Panurus biarmicus): the biology of a remarkable bird – a review of the recent literature

The Bearded Reedling Panurus biarmicus is a frequent, yet relatively little-known passerine bird found in wetlands across Eurasia. The species is difficult to study because of its elusive nature and the challenging access to its habitat: old, particularly dense reed patches standing in water. However, a detailed body of knowledge of the species’ natural history, morphology, and behaviour has been gathered over the years, providing insight into the adaptations this unusual bird uses to survive and even thrive under favourable conditions. In 2023, BirdLife Hungary named the Bearded Reedling as the ‘bird of the year’. In light of this notable designation, this article provides an overview of research advances on some of the unique characteristics of the Bearded Reedling, focusing on the factors that affect their population dynamics and potential conservation management strategies to protect the species.

“…This study investigated the chigger mite fauna in a small passerine, the bearded tit ( Panurus biarmicus ), inhabiting large reedbeds in extensive flooded marshes (Robson, 2007 ). Given that chigger mites can be responsible for, among others, restricted growth and loss of weights in birds (Literák et al ., 2001 ), and low weight associated with weakened health can contribute to marked fluctuations of bearded tit populations over time (Surmacki and Stępniewski, 2007 ; Stępniewski and Halupka, 2018 ), relationship between the sex, age and body condition of investigated birds, and the prevalence and load of mite larvae were also examined. We predict that increased mite loads lead to a decreased body condition in infected birds.…”

Chigger mite (Acariformes: Trombiculidae) infestation in reed passerine birds in Central Europe: a case of the bearded titPanurus biarmicus

Larval trombiculid (chigger) mites are common ectoparasites of terrestrial vertebrates including humans, causing itching and skin inflammation known as trombiculiasis. Investigation of their diversity, distribution and seasonal abundance is therefore important from a veterinary and public health point of view. Although researchers have paid increased attention to these parasites in recent years, there is still little ecological data available on chiggers associated with birds inhabiting different types of habitats such as wetlands, for example. In 2021, we investigated the mite fauna in a specialist reedbed passerine, the bearded tit (Panurus biarmicus), and their effects on this host in the south-west Slovakia, Central Europe. A total of 1134 larvae of 1 mite species Blankaartia acuscutellaris were found in 99 out of 267 examined bearded tits. Juveniles were more infested than adult birds, but no differences were found between sexes. The larvae of mites first appeared on the host during the second half of June and peaked in the second half of July. After that, their numbers decreased gradually until October. Despite the relatively high prevalence and intensity of mite infestation in the bearded tit, no differences in body condition between infested and uninfested birds suggest that infestation by B. acuscutellaris may not have serious negative effects on the host health. Bearded tits can therefore be a reliable indicator of the presence of the chigger mites in wetland habitats.
