“…Indeed, PACAP mimicked effects of forskolin, a direct activator of adenylate cyclase, on the actin cytoskeleton of astrocytes with resultant astrocyte morphological changes (Perez et al, 2005). In addition, PACAP is essential for lactate production and secretion in astrocytes, a central step in the neuronal physiology of hippocampal learning and memory (Kambe et al, 2021) the center for integrative information for familiar landmarks and landscape features in homing pigeons (Bingman and Ewry, 2020;Gagliardo et al, 2021), and for avian long-distance migratory journeys (Frost and Mouritsen, 2006;Barkan et al, 2016;Bingman and MacDougall-Shackleton, 2017).…”

For the epic journey of autumn migration, long-distance migratory birds use innate and learned information and follow strict schedules imposed by genetic and epigenetic mechanisms, the details of which remain largely unknown. In addition, bird migration requires integrated action of different multisensory systems for learning and memory, and the hippocampus appears to be the integration center for this task. In previous studies we found that contrasting long-distance migratory flights differentially affected the morphological complexity of two types of hippocampus astrocytes. Recently, a significant association was found between the latitude of the reproductive site and the size of the ADCYAP1 allele in long distance migratory birds. We tested for correlations between astrocyte morphological complexity, migratory distances, and size of the ADCYAP1 allele in three long-distance migrant species of shorebird and one non-migrant. Significant differences among species were found in the number and morphological complexity of the astrocytes, as well as in the size of the microsatellites of the ADCYAP1 gene. We found significant associations between the size of the ADCYAP1 microsatellites, the migratory distances, and the degree of morphological complexity of the astrocytes. We suggest that associations between astrocyte number and morphological complexity, ADCYAP1 microsatellite size, and migratory behavior may be part of the adaptive response to the migratory process of shorebirds.

Navigation is a complex task in which the hippocampus (Hp), which plays an important role, may be involved in interactions between different frequency bands. However, little is known whether this cross-frequency interaction exists in the Hp of birds during navigation. Therefore, we examined the electrophysiological characteristics of hippocampal cross-frequency interactions of domestic pigeons (Columba livia domestica) during navigation. Two goal-directed navigation tasks with different locomotor modes were designed, and the local field potentials (LFPs) were recorded for analysis. We found that the amplitudes of high-frequency oscillations in Hp were dynamically modulated by the phase of co-occurring theta-band oscillations both during ground-based maze and outdoor flight navigation. The high-frequency amplitude sub-frequency bands modulated by the hippocampal theta phase were different at different tasks, and this process was independent of the navigation path and goal. These results suggest that phase–amplitude coupling (PAC) in the avian Hp may be more associated with the ongoing cognitive demands of navigational processes. Our findings contribute to the understanding of potential mechanisms of hippocampal PAC on multi-frequency informational interactions in avian navigation and provide valuable insights into cross-species evolution.

Pigeons are showing remarkable progress with more profit. This sector has many potential markets in the country. After visiting some pigeon houses, many limitations have been come out. Many rearers collect pigeons based on only physical appearance, and in the long run, they cannot get pure offspring. King pigeon is considered a table breed in the world but in Bangladesh rearers keep them as a common fancy item. Pigeons do not get their nutritious food from the owners. Result suggests that many rare pigeons are caught by predators and due to unwanted dirt in those lofts birds are affected by many diseases. Some remarkable farms are showing quality environment in their lofts and getting desirable profit.
