Power source, data retrieval method, and attachment type affect success of dorsally mounted tracking tag deployments in 37 species of shorebirds

Author: Weiser, E.L., Lanctot, R.B., Ruthrauff, D.R., Saalfeld, S.T., Tibbitts, T.L., Abad-Gómez, J.M., Aldabe, J., Bosi de Almeida, J., Alves, J.A., Anderson, G.Q.A., Battley, P.F., Belting, H., Bêty, J., Bianchini, K., Bishop, M.A., Bom, R.A., Bowgen, K., Brown, G.S., Brown, S.C., Bugoni, L., Burton, N.H.K., Bybee, D.R., Carneiro, C., Castresana, G., Chan, Y.-C., Choi, C.-Y., Christie, K.S., Clark, N.A., Conklin, J.R., Cruz-López, M., Dinsmore, S.J., Dodd, S.G., Douglas, D.C., Eberhart-Hertel, L.J., English, W.B., Ewing, H.T., Faria, F.A., Franks, S.E., Fuller, R.A., Gill Jr, R.E., Giroux, M.-A., Gratto-Trevor, C.L., Green, D.J., Green, R.E., Green, R.M.W., Gunnarsson, T.G., Gutiérrez, J.S., Harrison, A.-L., Hartman, C.A., Hassell, C.J., Hoepfner, S.A., Hooijmeijer, J.C.E.W., Johnson, J.A., Johnson, O.W., Kempenaers, B., Klaassen, M., Kok, E.M.A., Krietsch, J., Küpper, C., Kwarteng, A.Y., Kw

Tracking studies, where individual devices are fitted to birds to follow their movements, are becoming increasingly common in ornithology. This paper uses previous research tracking waders to evalutate how various factors, including tag attachment type and power source, affect the likelihood that a study will meet its goals, and provides guidelines for selecting a tracking technique to optimise the chances of success.

Bioacoustics as a tool for the detection and monitoring of a scarce woodland bird – the Lesser Spotted Woodpecker

Author: Smith, K., Smith, L., Addleton, N., Clements, R., Fisk, S., Gillings, S., Mallalieu, M., Mathieson H. & Robin, A.

Published: 2025

Passive acoustic monitoring is an effective way of monitoring the elusive and declining Lesser Spotted Woodpecker, improving our understanding of the species’ status, ecology and the conservation actions that might reverse its fortunes.

Overwinter population estimates of waterbirds in Great Britain

Author: Caulfield, E., Woodward, I., Peck, K., Wotton, S. & Frost, T.

Published: 2025

Analysis of data from long-term monitoring schemes gives a total wintering waterbird population estimate in Great Britain of 12.8 million individuals for 2017/2018 to 2022/2023. While this total is unchanged from the previous estimate, there have been notable shifts, with numbers of estuarine waders, Whooper Swans, Little Egrets and non-migratory geese increasing, and declines in several duck and goose populations, including Bewick’s Swan, Pink-footed Goose and Teal.

Temporal changes to migratory fuel load in migratory birds across Europe

Author: Border, J.A., Robinson, R.A., Pearce-Higgins , J.W., Hewson, C.M., Howard, C., Stephens, P.A., Willis, S.G., von Rönn, J.A.C., Henry, P.-Y., Lorrilliere, R., Serra, L., Imperio, S., Gargallo, G., Baltà, O., Karcza, Z., Vangeluwe, D., Valkama, J., Perez, C., Bensusan, K., Fransson, T., Herrmann, C., Bairlein, F., Fiedler, W., Horton, J. & Baillie, S.R.

Published: 2025

Data from bird ringing show changes in the timing of birds feeding up before their autumn migration across Europe over the past 40 years, and a decrease in the extent of fattening recorded. This decline was strongest in southern Europe and was linked to rising temperatures associated with climate change.

Solar radiation affects bird distributions but not elevational shifts in European mountains

Author: Couet, J., Marjakangas, E.-L., Andrea Santangeli, A., Niittynen, P., Fontaine, B., Herrando, S., Kålås, J.A., Lindström, Å, Massimino, D., Moosmann, M., Seaman, B., Silva, L., Stokke, B.G., Teufelbauer, N. & Lehikoinen, A.

Published: 2025

Research involving BTO shows bird species moving toward colder areas in the mountains of Europe as the climate has warmed over the past two decades.
