The Challenge in the Joy of Learning: Batumi 2018

By Paulina Camarena, 2016 Conservation Science Trainee
Hawk Mountain Sanctuary

I still remember the time at Hawk Mountain, when one of my now best friends and colleagues in raptor conservation, Aneesha Pokharel, was slightly worried about identifying North American raptor species as she is from Nepal and those birds would be completely new to her.  Now it was my turn.

As a field biologist focused on bird monitoring, particularly raptors, I have monitored migrating raptors in the Isthmus of Tehuantepec in México, my home country, in addition to being an intern at Hawk Mountain in the spring of 2016. However, the time to jump into unknown species to me appeared recently.  I found out that the Batumi Raptor Count (BRC) was seeking volunteers to monitor the migration from August to November in Batumi, Georgia. Despite knowing it was going to be a challenge to count and identify species I have never seen before, I decided to apply, and I cannot be happier about having taken that chance.

My first day was August 12, 2018, and my journey to Batumi has been the longest I have ever taken to reach a place. As I was in England, I took a flight from London to Amsterdam, then to Istanbul, and finally, being the most affordable option at the moment, I took a bus to Batumi. I spent 24 hrs in that bus! Despite the long hours and stressful moments—absolutely no one spoke English nor Spanish in the bus—I gratefully remember how some people helped me in many ways. Finally I was there, in my new home for the following two months: Sahalvasho in Batumi.

Honey buzzards, steppe buzzards, black kites, marsh harriers, Montagu’s and pallid harriers… among many others. They looked so similar to the new, unskilled eyes. The first days felt absolutely slow, with quiet early mornings and long hours with not many birds yet decorating the sky, plus the pressure of learning to ID the species. There were two observation points: Sahalvasho and Shuamta. Station 2, Shuamta was my favorite since the beginning, as the height was just a pleasure in addition to the landscape, and for the ones who have been there, we know the hike up is not precisely easy at all times but certainly rewarding. Step by step, day after day, and thanks to the people I was surrounded by, I started to pick up the species I was watching. However, I have to admit it took me a while to feel confident enough to say “Palmtop” and register the species I was seeing cross the transect line. While watching a bird through the binoculars and thinking “that’s a marsh harrier" to then hear  “marsh harrier!” by someone else, I knew that I was successfully learning  and in those moments I felt such joy. The days started to go faster, and the number of birds counted day after day increased.  To watch and be able to discern between Montagu's and pallid harriers was a rewarding experience but definitely not an easy one, among many others, and was the result of the everyday practice.

 During my stay at Hawk Mountain, I learned significantly about vultures and their critical conservation status, and they became among my favorite group of birds. I will never forget the moment at Batumi, when a griffon vulture circled among an enormous kettle of steppe buzzards just in front of us, and another memory made by a moment when, after some light rain around Station 2, raptors flew by so close to us that we felt we could almost touch them. In no place before I have seen raptors flying by so close. The time of the eagles also arrived, and watching hundreds of them flying above us was also memorable; these are the things that make you feel you are a lucky person.

Over a million raptors were counted this season, however Batumi was not only the birds. The BRC is the people from many countries and a variety of backgrounds, reunited to contribute in raptor conservation; it is the charming Georgian families who hosted us and the delicious food that was on our table on every dinner time. It is the sharing of knowledge and experience, for sure an amazing learning opportunity for everyone.

Monitoring Migration in Eilat, Israel

By Ana De Osma Vargas-Machuca, Autumn 2016 Conservation Science Trainee
Hawk Mountain Sanctuary

A month ago I came back home from my Israeli adventure, where I have been monitoring the spring raptor migration in Eilat, a dream came true.

This all began in 2011, when I met Re'a Shaish while volunteering in the Migres Program in Tarifa, Spain. He is an Israeli guy who was extremely passionate about birds, and at only 19 years old was able to identify every single species of raptors flying over us. He told us about Eilat and the migration there, and since that moment Eilat had been always on my mind.

Last year we met again in Extremadura for a couple of days, where he was assisting Yoav Perlman with his field work, and both of them told me again about the spring migration in Eilat. I was working as a biologist in Spain, but it wasn't anything related to conservation biology. I greatly missed being in the field, so at the end of the year I arranged to be off from work in the spring and contacted Noam Weiss (the director of the IBRCE) to apply for a position as a counter in the raptor team. When I got his reply telling me that I was accepted, I was elated.

So there I was at the end of January, flying to Eilat, watching through the window the beautiful Negev desert, getting goosebumps and feeling excited for all of the experiences to come.

We were two teams of volunteers: the raptor counters, working mainly at the stations in the mountains, and the ringers and guides, working at the sanctuary.

The first of February was the first day of the count. The count was conducted by four of us (Daniel, from UK; Gaidis from Latvia, Ragnar from Denmark, and myself), divided in two stations, Low Mt. and High Mt. Station, both of them in the Eilat mountains, close to the Egypt border.

At the beginning of the season, the migration was still very low, so those not counting would have the chance to go to the sanctuary to assist with other work or to just bird around. I remember the first day being at High Mt., and even if I had no birds migrating, I felt so grateful for just having the chance of being there, in such a beautiful office, with Jordan on the east, the Red Sea and Saudi Arabia in the south and Egypt in the west.

Some brown-necked ravens, Tristam's starlings, two dessert larks, a hooded wheatear, and a very nice juvenile white crowned wheatear were our regular visitors who sat at the station and kept us company. On those days of counting steppe eagles in February, there were some amazing days with birds flying overhead, very close to us. Such incredible creatures in that stunning landscape... I was happy no matter what weather I had, how many eagles were migrating or how many people visiting; being there was just amazing.

In February we would finish work before sunset and still have time to go to the beach for some snorkeling before the light was gone. We lived in the Field School, right in front of the beach near the Taba border with Egypt, so coming back home from the mountains and walking to the beach with the guys for some snorkeling was our daily afternoon routine. We found some spots with well-protected coral reef and snorkeling there with all of those beautiful fish was delightful.

First week of March, I was selected together with Anton (a Danish ringer) and Ohad (Israeli birdwatcher) to be part of the Arabian warbler survey taking part in the Arava Valley, close to Hatzeva (2 hours north to Eilat). This survey was very important, as there is very little information about the species, and the first and last survey was on the 1980, conducted by the SPNI. We walked around 10-15 km everyday in the desert, looking for Arabian warbler territories but also recording every bird species around, but this incredible opportunity of going where few have had the chance to go felt like a holiday. It was really special to be surrounded by that nature, and at the same time to know that we were making an impact for the species.  We actually found more new territories than they were expecting, and I feel very thankful to Noam, Inbar, and Eli for letting me be part of this.

The rest of March flew by, and the migration came to peak time. Steppe buzzards, black kites, black storks together with other species started to pack the skies. Days became longer, counting from sunrise to sunset. It was exciting and exhausting at the same time, but we were happy no matter how tired we were; having those numbers of raptors migrating in front of you gives the energy you need to keep clicking and counting. And that's what we did until the 10th of April when we completed the count.  From the 12th -14th of April we were part of the Raptor breeding survey, and we finished work the 15th.

After that I went traveling around the country, spending most of the time enjoying the north (Hermon mountain, Golan Heights, Hula Valley), and it was so different from the desert I had worked in. I returned to Spain at the end of April.

It's difficult to summarize in a post a 3-month experience, so I hope at least I gave you a brief feeling of how it was. Not everything was just work, there were also days off, and I spent most of them going hiking in the Eilat mountains, where there was much to explore and see.

Israel is a beautiful country with very warm and welcoming people, and felt at home from the start. Thanks to everyone who made this experience so amazing for me: my teammates, all of the special people that stop by High Mt. station, Frank and his lovely company, Libi and Tdazok, but specially Noam and my good friend Re'a; without them none of this would have happened. 

Shalom!

Late Migration Mountain Musings

By Dr. Laurie Goodrich, Director of Long-term Monitoring
Hawk Mountain Sanctuary

“… break clear away, once in awhile, and climb a mountain or spend a week in the woods. Wash your spirit clean.”  - John Muir

Migration flow slows in late November and December, with some days seeing barely a trickle.  But, nearly half the birds we count can be eagles, bald and golden.  Because thermals are rare, the eagles hug the ridge so close that they seem to barely clear the treetops. And, late season days are the only time I have ever seen a northern goshawk or northern harrier strafe the decoy owl.  December is often the best time to see rough-legged hawk, an arctic nesting species that rarely visits Pennsylvania, and one of the rarest raptor migrants. And, northern nesting songbirds such as red and white-winged crossbills are often only seen on these late season days.  Despite these exciting possible sightings, the visitor numbers diminish drastically at this time and counters are often found alone on the rocks.

Thanksgiving Day, November 23 2017: My sister calls me 9 am.  She asks “where are you having thanksgiving dinner?” I tell her I am going to count hawks in afternoon, though a volunteer is working there this morning.  She is audibly horrified, “they make you count on a holiday? “

“Well…” I say, “ I cannot ask a volunteer to be there, although one is there for the morning. And, other staff have covered other years so it is my turn….” She is quiet and I can tell she is feeling sorry for me, so I say, “and the birds still fly south even on holidays.”  

Secretly, I don’t tell her I am looking forward to my afternoon “on the rocks”.  Later that day I count nine red-tailed hawks and an adult bald eagle gliding south and greet nearly 100 visiting hikers on a sunny Mountain day, sharing my Thanksgiving pumpkin bread. 

Since the 1980s, Hawk Mountain staff and volunteers have manned the North Lookout daily from mid-August through mid-December for the annual autumn migration count.  However, in the early years the season began September 1st and ended November 30th. As we learned more about raptor migration timing, we realized a longer season was needed to fully sample the raptors, particularly eagles and buteos, so we extended the hawk count.

Bald Eagles have a bi-modal migration with two peaks, one in late August or early September and one in November.  The early eagles are the southern nesting race, that begins nesting in late fall in southern states, while the later birds are the northern bald eagles that nest in New England, Mid-Atlantic and northward.  The northern birds often do not move south in large number until waterways start to freeze up north.  If we have mild autumn weather, we often can have double-digit daily counts of bald eagles into mid-December, which for a species where we record 300 to 500 annually can make a large difference in annual totals.  Golden eagles also can be observed into December with the golden-tinged adults more likely at this time.  Add in an adult goshawk or rough-legged hawk and you have the makings of a great day.

Late season counting is also a great time to ‘wash the spirit clean’ as John Muir states.  The forest is often quiet save for the occasional common raven or pileated woodpecker call.   The skies can be still, save for the occasional raptor or skein of snow geese or tundra swan passing by.  When the sun hits the rocks, sometimes frosted with snow, the peace and beauty of the Mountain can recharge.  Though I hesitate to share this secret of Hawk Mountain, these late season days are worth a few hours time, whether there are migrating raptors or not.    

On that note, happy holidays everyone, and be sure to join us in the Spring!
