Hermon day 2 - Irania

Today I went with my team to survey Mt. Dov, which is a part of Mt. Hermon rarely visited by civilians. This is an extremely sensitive military area, and we were very lucky to get the chance to survey the rich habitats there. The military patrol escorting us was very cooperative and helpful, which was very good.

The first couple of hours in my box were extremely good with lots of birds and many species, and I documented lots of breeding activity. As everywhere in the lower elevations of Mt. Hermon, most dominant species were Lesser Whitethroat and Sombre Tit. I was happy to see two Black-headed Buntings - fresh arrivals, and always great birds to see:



Other highlights included Syrian Serin, Rck Nuthatches, Cretzschmar's Buntings, several Eurasian Cuckoos and Balkan Warbler. Again several breeding pairs of Red-backed Shrike - here is a female:



Migration was much more evident today, with lots of Blackcaps, Willow Warblers and three Golden Orioles on the ground, and massive raptor migration overhead, consisting mainly of Steppe and Honey Buzzards, Lesser Spotted and Booted Eagles, Black Kites and Levant Sparrowhawks.


Just as we were about to leave we spotted a male Irania (White-throated Robin) - I saw it only briefly but heard it singing. I was very happy to find this rare breeder so early and rather low.

Other animals included again Levante Fan-fingered Gecko, a huge Medium Lizard (Lacerta media) that disappeared before i was able to photograph it, and feces of Wolf and Beech Marten.

Many thanks to Dudu for his help and company.

Mystery Chiffchaff update: this afternoon Noam and Amir Ben Dov returned to the site where we had them yesterday. They found a staggering 10 singing males, and had better views that what we had yesterday.I cannot open Amir's RAW images on my computer, so his much better images should be online in a few days. Looking good.

Hermon day 1 - boom - Mountain Chiffchaffs!?!?

Day 1 of Hermon breeding survey began with quite a mess. Early in the morning I dropped off Noam and his fantastic kids at their box, and continued to my adjacent box. I descended a steep mountain with my 4X4 down a horrible track, that just became worse and worse, until it eventually disappeared. I had to reverse back up over some very challenging obstacles, until I could U-turn, which took me about 15 minutes. Then another 15 minutes to climp a steep step, and in the process ripped a tire, that we had to change in tough conditions. So the first hour was from hell. Eventually managed to drive towards my box, when it was already very late - hot and windy. We met up with Noam, and he told me "I've just heard a funny chiffchaff...". I stopped and quickly heard the bird too, and immediately my alarm bells went off - sounds like a Mountain Chiffchaff, a song I remembered from xeno-canto! We all started obtaining some views, then photos and recordings. The bird was very mobile and elusive. It was very hard to see but eventually we got very brief but OK views. The bird was striking brown, with no apparent green fringes to secondaries; nice whitish supercilium; whitish throat with some buff wash on breast sides. In the image below the sun was direct but in the field the bill and legs looked solid black. The mantle and rump were rather rich brown. Also the cap.
the song was to my ears different from typical collybita, with a more energetic tempo and winding quality:

The bird responded well to Mountain Chiffchaff playback, and didn't respond to 'normal' Chiffchaff playback.

Thanks to Zohar, Noam's son for this great image - much better than I managed to get: 


After spending about an hour trying to photograph the bird without success, I left Noam and continued to my box. Amazingly, Noam had another three singing bird nearby, and later on I had another about a kilometer away. All birds singing males; at least the male we were able to see performed territorial behavious, including chasing away other (much larger) birds. Incredible.

I am sure that these birds will stir a good ID discussion. Mountain (AKA caucasian) Chiffchaff is extremely rare in Israel, with only two previous records. Which is quite surprising given how close to Israel they breed. Anyway, if these birds are confirmed as Mountain Chiffchaff, this is quite sensational. So guys, bring your comments on! Learning time.

When I eventually began working my box with Dudu, we saw quite many birds. The scenery was quite spectacular, everything still flowering and fresh, so different from around my house where it really feels like summer already. Most dominant were Lesser Whitehtorats and Sombre Tits. Other quality birds were Upcher's Warbler,  a breeding pair of Steppe Buzzards, and a pair of Crag Martins.  Some raptors went overhead, including some levants.
