European Union for Bird Ringing - co-ordinating organization for European bird ringing schemes. Promotes research, data sharing and technical co-operation.
EURING is delighted to announce publication of the Eurasian-African Bird Migration Atlas migrationatlas.org based on @_EURING ring recoveries and tracks from @MovebankTeam The Atlas was developed in collaboration with @BonnConvention and funded by the Italian Government
Our latest recovery is of a juvenile male Siskin ringed at Ramsley Reservoir, Derbyshire in July 2023. It was retrapped in January 2024 at Andijk, The Netherlands, a distance of 458km east in 184 days @_BTO@shefbirdstudy@Derbyshirebirds
We are already in October, but some of our #WhiteStork fledglings are still reluctant to cross the Straits! Although named after a Portuguese island, Berlenga - unlike many famous Portuguese sailors - does not seem to be at the forefront of European overseas exploration!
📣 🐔Just published | New quarterly monitoring report on #AvianFlu: the situation in poultry & wild birds has eased over the summer ☀️
However, there’s been a resurgence in seabirds along European coasts.

We are looking forward the the EURING General Meeting 2024 that will be held in Tata, Hungary. Over 80 people will be attending and most European Ringing Schemes will be represented. See euring.org/meetings/general-… for more information

After >20 years of tracking, our ringed black-tailed godwits have revealed that the autumn and winter sites used by juveniles are (nearly always) the ones they will use throughout their lives.

We only have three small Storm-petrel chicks in the study boxes on Nólsoy at the moment, with 38 boxes having had eggs laid! Others will certainly hatch in the next week, but it’s very interesting to observe how late the season is this year. Anyone else found the same?
Nonparametric statistical methods offer powerful tools for analyzing data without making strict assumptions about the data's distribution. These methods are versatile and can be applied to various types of data, providing robust results even when traditional parametric methods fall short.
✔️ Flexibility: Nonparametric methods can handle data that doesn't fit normal distributions, making them ideal for real-world situations.
✔️ Robustness: They reduce the risk of errors by not relying on assumptions about data distribution.
✔️ Applicability: Useful in small sample sizes where parametric methods may fail.
❌ Limited Power: Nonparametric methods may have less statistical power compared to parametric tests, especially with larger sample sizes.
❌ Complexity: They can be more complex to interpret and require careful consideration of the method chosen.
❌ Computation: Nonparametric tests can be computationally intensive, particularly with large data sets.
Key Nonparametric Methods:
1️⃣ Mann-Whitney U Test: Used to compare differences between two independent groups.
2️⃣ Wilcoxon Signed-Rank Test: Applied to compare two related samples or repeated measurements on a single sample.
3️⃣ Kruskal-Wallis Test: An extension of the Mann-Whitney U Test for comparing more than two independent groups.
4️⃣ Spearman's Rank Correlation: Measures the strength and direction of association between two ranked variables.
5️⃣ Chi-Square Test: Used to examine the association between categorical variables.
Applying Nonparametric Methods:
🔹 R: Use the wilcox.test() function for the Wilcoxon test and kruskal.test() for the Kruskal-Wallis test. The ggplot2 package can help visualize results effectively.
🔹 Python: Leverage the scipy.stats module for tests like the Mann-Whitney U and Kruskal-Wallis. Visualize data with matplotlib or seaborn.
Would you like to dive deeper into nonparametric methods and explore a wide range of related topics? I've created a comprehensive online course on Statistical Methods in R that covers these concepts in detail.

Excellent day @spurnbirdobs chaperoning Lars Svensson around the ringing sites at Church Field meeting @TimsBirding and at the Warren with @SBO_Jason & @CharlotteFoote5. It all got too much for @Duerdenc1 who was blown away with the occasion! #Migfest24

New paper out in @JBiogeographydoi.org/10.1111/jbi.14996! We compare some 15 years of GPS tracking and citizen science resighting data of Bewick's swans, to see which contains more information on population space use. GPS data substantially outperform resightings. Nonetheless...

It's been a nice wader summer here at Ottenby, and >5000 have been ringed. Most adult birds have passed by now, and the juveniles are taking over - like this beautiful Broad-billed Sandpiper. #birdmigration#birdringing#birdbanding#autumnmigration#ottenby
