Last friday in Tzora, we had a pretty normal session with 91 birds. Two birds of note were a juvenile Woodchat Shrike and a Little Bittern.
One of the participants, Rafi, showed us something very interesting about one claw on each of the Bittern's feet, a tiny comb.
The comb is used for grooming, and is found on most Egrets, Herons and Bitterns.

The Shrike was the first Woodchat Shrike ever caught in Tzora, but definitely not the last, not even for friday.

After we finished folding all the nets, Yosef told us that they were going to drive around trying to catch more shrikes using baited traps. I went in Yosef's car and Chanan in Rafi's.
As we started driving, we saw our first one standing on a wire, a juvenile looking for something to eat. we slowly stopped the car and put the trap out, waited for a few minutes and... it flew away. We continued driving and found an adult standing on the continuation of the same wire, put the trap out, waited (this time for much longer) and sure enough it came down tried to take the grub and *SNAP* it got caught. Great, we had one but we still had a bunch of grubs, time and patience left so we kept driving.
After around an hour of driving, a few uninterested shrikes, two Stone Curlews and a Short-Toed Snake Eagle, we started heading back.

On our way back we found another juvenile and put out a trap. The bird flew down, took the grub and flew away to a wild raspberry bush to eat it! Yosef and I were both annoyed but took advantage of the fact that the bird was eating to quickly reload the trap and put it out. The bird finished eating and went right back to the trap, this time without any caution. It yanked on the grub, triggered the trap and we had caught our second shrike!
We headed to the rendezvous to meet with Rafi and Chanan (they hadn't caught any), ringed and photographed the birds and let them go.

When we reached the final cotton field of tzora, we saw quite a few Woodchats. Seeing as we had a few grubs left we decided to try and trap a few. Both times that we caught the birds, they managed to steal the grub the first time and only get caught on the second try. Both birds were juveniles that were at different stages of a full moult, one was almost done while the other was just starting. What's special about this is, that according to all literature known to Yosef juvenile Woodchat Shrikes only perform such a moult after their arrival in africa, so this really was exciting. Yosef set up his special sophistacated "WPS" (Wing Photography Studio) and took pictures of the wings of both shrikes.

So what started out as a pretty monotonous ringing session turned into an exciting adventure and an incredible discovery- a great day!
