Migration Count Data

Daily Totals

Our annual autumn count runs from August 17th until October 16th. During that period you can find our daily and season totals updated daily on Trektellen.org and embedded below on this page. These are our raw results, uncorrected for ‘double counts’: birds counted from both stations. We distinguish raw and unprocessed data, with these double counts, from cleaned and processed data, without double counts.

You can browse the daily totals below. If, for some reason, the daily totals don't show, click on the images to browse the results on Trektellen.org directly.

Annual totals

As of July 2018, every year since the autumn count of 2012 we have surpassed the million birds threshold, firmly placing Batumi amongst the world's biggest raptor migration bottlenecks. Figure 1 shows the processed totals (corrected for double counts).

To monitor the Batumi bottleneck and count more than a million raptors in a 2-month season, we depend on the generous support of donators, our BRC Members and many volunteer counters and coordinators. Want to help us?

Raw totals per year
of all monitored birds

The raw totals of all monitored raptors can be found in Table 1. The raw totals of other migrants included in our monitoring scheme are shown in Table 2.

Entries of ** indicate that species has not been monitored in the corresponding year.

Both tables are large and can be scrolled through. If you prefer, you can also download raw totals for both raptors and other migrants in a PDF file.
