Global Big Day in southern Extremadura

Yesterday was Global Big Day, organised by eBird. As we are working in southern Extremadura, we opted for a local big day. Our team included my two assistants Dan and Re'a, and our good friend and ace local birder Fergus. We had planned a route that will give us enough time to look for the typical birds of each main ecosystem / biome in southern Extremadura - steppe, woodland and wetland.
I was the driver and eBird checklister. I eBirded all birds we saw, which also helped us to keep track of species and know our daily total. Despite staying local in Badajoz, we still drove over 600 km and it was a loooooong day. I had very few photo opps - that's how it goes on big days.

We started at dawn right outside Merida, at Esparragalejo and Montijo dam. Picked up most herons and resident waterbirds pretty quick, and first quality of the day came in the form of three singing Western Olivaceous Warblers at Montijo.
We then drove south and checked the vineyards and olive groves south of Almendralejo. Our main target there was Rufous Bush Robin. Was really good to see - our first of the trip. They are so nice and rufous here, much brighter than the syriacus we get in Israel. A fine bird and a bimbo for Dan.

Then we moved on to the Hornachos - a mountainous Dehesa region. We did spend several hours there, and racked up most important species. Highlights included Western Orphean Warbler (as well as Dartford and Subalpine), Spanish Imperial Eagles, Black Wheatears, 4 Chough and couldn't find Cirl Bunting, again! Hornachos were hard work, and we did work hard for almost every species we needed. But eventually our day list increased there considerably. I missed a viral photo opp - this chicken swallow was waiting to be fed by its dad, who chose to feed its sibling to the right.


We then headed over to the steppes of La Serena. It was already early afternoon, but luckily yesterday was a rather cold and overcast day, so bird activity was alright. We knew the area well after working there in recent weeks, and we got our targets fairly quickly - both bustards and both sandgrouse. It took us depressingly long to get our first Roller - so few of them around.
This Calandra Lark sat still for just long enough for me to pap it.

After La Serena we headed north to Santa Amalia ricefields, via some embalses (dams). We were very disappointed with waterbirds - no new shorebirds or ducks. No migration at all. Along the way we did pick up some more random species.
Azure-winged Magpie is very common everywhere but I hadn't had a chance to get a photo till yesterday. Here it's true nature is exposed - a trash bird. But I still really like them.



We then headed down to the Guadiana river valley where we checked a couple of spots and added missing species such as Savi's Warbler and Little Bittern.
After dusk we searched for owls and nightjars south of Don Alvaro. Owls didn't play ball but Red-necked Nightjars put on quite a show. We had four singing males. One male flew up to a large Eucalyptus above us and started singing its somewhat manic 'tok-tok-tok...' song.


Then I got a more standard photo of another on the track - too distant so light was very weak.


We ended the day drinking beer on Fergus's balcony, listening out for owls. No owls came, but the beer was cold and the night was very pleasant. A lovely way to end a terrific, yet extreme and intensive day. It was hard work all day, nothing came easy. There was a complete absence of migrants - landbirds, shorebirds and ducks. Still, our daily total was 127 species - not too shabby I think. 
Huge thanks and appreciation to my team mates Fergus, Dan and Re'a. They all worked hard, found top birds and maintained high spirits all day long. Till next year!

Migrants at last

A couple of days ago we left Castro Verde and headed north. Before leaving CV we worked in some peripheral sections of the SPA that were less rich than the central sections we had worked in. It was sort of an introduction to the low densities of steppe birds in the cereal and montado landscapes of northern Alentejo. We still had some bustards, larks and other steppe species but in smaller numbers.

One for Dan - Clouded Yellow

Campo Maior, where we are based, is a lovely and picturesque town from Roman times. It has one of the largest castles in Portugal, and we live in a small apartment right below the castle. 



Every day we head out to survey the remaining patches of agro-steppe habitats in northern Alentejo. The region has transformed quite a bit since I last visited in 2015. More intensive agriculture, more permanent crops. And less birds. Near Campo Maior the small group of Great Bustards somehow holds on, but in Torre de Bolsa they are gone. Little Bustards are found in low densities. Sometimes they are found in sub-optimal habitats, and sometimes in really weird places. This poor male sang his little sad heart out in the middle of a recently-cut wheat field:

Still it's a pretty landscape

Today we worked near Elvas. I found a small, loose colony of Collared Pratincoles, about 15 pairs, breeding in a potato field. They kept their distance in the middle of the field:


There are quite many Montagu's Harrier in this region (I even had a black-morph flyby today). Every time one passed over the potato field it was aggressively seen off by a horde of angry pratincoles:



Our points and transects today flanked some better vegetated habitats, and in them it was clear that suddenly there were migrants around, probably knocked down by some pre-dawn rain. Among the three of us we had Willow Warblers and Iberian Chiff, Western Bonelli's, Whinchats, Savi's Warbler, Spotted Flycatcher, Tree Pipit, Garden Warbler and a few more. Nice! Today's eBird checklist is here. I had my lifer Red-necked Nightjar today - a day-roosting bird found by Dan; it didn't stay for photos sadly. Another cool bird we had a few of today is Melodious Warbler. One male showed really well as he sang on top of low vegetation, but the light was rubbish.

Recent rambling

Last few weeks have been really busy but not really with birds. At least not living birds. Last week I spent a few days in Frankfurt - my 97 yo grandmother Helene had passed away. May she rest in peace - she was a brave and strong woman. She had a tough life, that included surviving WW2 and starting new lives in too many countries,; her strong character and will is truly inspiring to my family. Here she is with her brother Hermann in 1932, when she was 13:


While organising her funeral, I found some time to go with my brother to Senckenberg Museum of Natural History. When I last visited there in July 2016 I discovered a potentially interesting wheatear. I did not take full measurements back then, so this time I took the full biometric set. Hopefully soon its identity will be determined.

I took the opportunity to look at some more nightjars. I am involved in a large nightjar phylogeny project with Prof. Martin Collinson from University of Aberdeen. One of the things we want to check is Red-necked Nightjar phylogeny. The two subspecies - ruficollis (Iberia) and desertorum (N Africa) look strikingly different, and possibly have different vocalisations too.  This is a simplistic morphological comparison - males, ruficollis (left two) and desertorum (right two):




The last few days have been all about Champions of the Flyway. Sadly, I could not go this year, but did my best to support the project from here. It was yet again a fantastic race and event, well done to the organisers, teams, donors and supporters worldwide.

Jonathan!

Yesterday morning I had a frustrating experience. After schoolrun I walked with my dog in Heigham Park that is near our house. I heard from the bottom of the park a 'funny' Chiffchaff song - 3-4 sequences. The soft initial notes sounded good for Iberian Chiff, but I couldn't hear the terminal trill from that distance. I approached the bird and got my phone ready to sound record, but it went silent and I did not see or hear it again. Eventually, I cannot exclude a 'funny' normal Chiffchaff, so will leave it like that.

In about 10 days I am going away for fieldwork in Spain and Portugal, so expect an increase in blogging frequency!
