Rain-ging, again! but with many more birds

9th
A decent mornings ringing with a steady stream of birds up until the nets were closed at 12:30. An Adult female Ruppell’s Warbler Sylvia ruepelli סבכי שחור גרון and 3 Bonelli’s Warbler Phylloscopus orientalis עלווית לבנת בטן  were among the 106 birds caught. Visible migration was almost non-existent and a Song Thrush Turdus philomelos קיכלי רונן  was the pick of the migrants seen on the ground.

The main talking point of the day was the weather. Some light rain showers during the course of the morning turned in to a real storm shortly after midday. Although the northern European volunteers are used to it, this was quite exceptional weather for Eilat. The rain continued for most of the afternoon and, with more forecast for overnight, we had to abandon the ringing station and spend the night in town in case we were cut off by rising water in the channels surrounding the site. Instead of birding we went "rain watching" in Eilat Mountains.

MEGA- a puddle in the entrance of the ringing station!

We arrived back on IBRCE before dawn to find everything still in its place albeit a little damp. Yesterdays rain had cleared the air and the views to the mountains to east and west were spectacular. The nets were opened and the birds trickled in throughout the morning. The total of about 90 birds included Eastern Olivaceous Iduna pallida שיחנית קטנה , Ruppell’s Sylvia ruepelli סבכי שחור גרון and Eastern Bonelli’s Warbler Phylloscopus orientalis עלווית לבנת בטן but the most captured species continue to be Lesser Whitethroat Sylvia curruca סבכי טוחנים, Sedge Warbler Acrocephalus schoenobaenus קנית פסים and Spanish Sparrow Passer hispaniolensis דרור ספרדי .

Overhead there was much more interest today. Flocks of migrating swifts and swallows were a constant presence including over 200 Alpine Swifts Apus melba סיס הרים heading north during the morning.

Booted Eagle Aquila pennata עיט גמדי , numerous Steppe Eagles Aquila nipalensis עיט ערבות, an adult Greater Spotted Eagle Aquila clanga עיט צפרדעים and a single Black Stork Ciconia nigra חסידה שחורה were all noted. There were no big numbers of raptors but following many days with almost none, it was a start, and hopefully a sign that there is more to come in the next few days.

11th
Today is the Israeli "good deeds day". The nets were open for 6 hours and produced just short of 100 birds (not such a good deed, we expected the birds to behave better!). Despite their lack of cooperation, many of the birds today were shown to the public. This helps us to spread our ideas about nature conservation, the importance of Eilat as a migration stopover site and to educate people about the ringing process and its benefits. Thanks to our collaboration with the salt factory "Salt Of The Earth Ltd." and SPNI we were able to give free guided tours to a group of 10 special education kids and another tour for almost 70 seniors from Eilat city. IBRCEs good deeds done!

More Ruppell’s Warbler Sylvia ruepelli סבכי שחור גרון were around with 3 males caught along with 5 Penduline Tit Remiz pendulinus רמית.

Migration was a little slower than yesterday but swallows, particularly Red-rumped Swallow Cecropis daurica סנונית מערות and House Martin Delichon urbicum טסית בתים, continued to pass through with small numbers of swifts. A Pallas’s Gull Larus ichthyaetus שחף עיטי flew north early morning with a small flock of Lesser Black-backs Larus fuscus שחף שחור. A second calendar-year Eastern Imperial Eagle Aquila heliaca עיט שמש drifted north during the afternoon was perhaps the bird which has been lingering in the area.

128 birds found their way into the nets, the highlight being the first Eurasian Scops Owl Otus scopus שעיר מצוי of the season.

Sylvia warblers dominated the catch making up just over 50%. These were mostly Lesser Whitethroat Sylvia curruca סבכי טוחנים but also a noticeable increase in Blackcap Sylvia atricapilla סבכי שחור כיפה and another 4 Ruppell’s Warbler Sylvia ruepelli סבכי שחור גרון.

A re-trapped Cetti’s Warbler Cettia cetti צטיה was a bit fatter and 2 grams heavier that when it was caught last month so is perhaps getting ready to leave IBRCE for its breeding grounds.
9 Eurasian Spoonbills Platalea leucorodia  כפן לבן on the saltpans early morning were new arrivals but soon flew off north. Overhead were good numbers of raptors. Among the usual species were 2 Egyptian Vulture Neophron percnopterus רחם and a small wave of over 50 White Stork Ciconia ciconia חסידה לבנה also headed north.

Not only feathers
Death's-head Hawkmoth Acheronita atropos רפרף גולגולת המת

We have noticed nice numbers of Hawk Moths recently (like in most springs around IBRCE) Most common were the Oleander Hawk-moths Daphnis nerii רפרף ההרדוף but every now and then we get the rarer Death's-head Hawkmoth Acheronita atropos רפרף גולגולת המת.
