Delaware 2013, Part 2 – a.k.a. the knot are beginning to arrive post

At the Wednesday evening team meeting, the offer was extended for people to join Bracken (local staff member) on Thursday morning with some breeding bird point counts in Maryland. I initially baulked at the 4am start time but the pull of warblers was just too strong and I soon capitulated! So, well before dawn on Thursday I was sleepily getting into a car with Bracken and Rob. We headed off and before 5am found ourselves in a Wawa’s, an American coffee shop chain. Needing a sugar rush to wake me up, I decided to take my life into my own hands and order a salted caramel hot chocolate. Within a couple of sips, I was bouncing off the walls of the car! I think it is quite possible that that one drink (I got the smallest possible) contained my entire daily calorific allowance!

The point counts are part of the US survey methodology for potential wind farm sites (another reason I was interested). The site is at the very early stages of survey and the potential location is not yet finalised so a 10 mile by 5 mile survey area is being covered. Sixteen point counts have been chosen at random across the area and surveys involve standing at the points for five minutes and recording all birds seen or heard. The counts are undertaken weekly between April and July. Additionally, migration surveys are carried out in the autumn. Presumably, more robust surveys are then undertaken when the location of the wind farm has been ascertained (we did suspect that the met mast at one location may be a clue as to the current favourite spot!).

After the surveys were finished, Bracken called in to Kevin to find out what was happening. The answer was a familiar one – still no knot in the harbour, therefore, not a lot happening. With this in mind, we headed back towards Delaware and took the opportunity to do a little birding in the management reserve area of Little Creek. It was a beautiful morning and the birds were singing their little hearts out and showing nicely. In total, I added twelve new species to my American bird list (not that I am a lister of course!) including black and white warbler, bay-breasted warbler, chestnut-sided warbler, magnolia warbler and Canada warbler. We also nearly trod on a plethora of common toad and found a very cool box turtle! As if that wasn’t special enough, we quickly popped into the St Jones Reserve on the way past for Bracken to show us the black vulture chicks nesting at the bottom of a hollow tree. The only way to describe them is that they were so ugly, they were cute! The only problem with wandering through woodlands, however, is the nasty, horrible ticks - I found four of them crawling on me when I got back to the house.

Later that afternoon, a small team of us went colour ring re-sighting at Port Mahon. It was blisteringly hot and the biting flies were evil. Re-sighting at Port Mahon is tricky as the birds are amongst rocks which keep hiding their legs. The beach is also a stone’s throw away from the road and the birds there can be easily disturbed by passing traffic. Despite this, we managed to get a few flags to contribute to the database.

Friday morning woke up bright and sunny and proceeded to be a gorgeous, stiflingly hot day. The sense of déjà vu was beginning to wear thin as, again, the early morning recce team found few knot in Mispillion Harbour. The planned knot catch on Back Beach was postponed once again so I spent a bit of time out on Slaughter Beach watching the birds out there. They were mostly semi-palmated sandpipers and dunlin with a few turnstones thrown in. A few of the birds had flags on but they were too far away to see and very jumpy when I got too close.

When the tide was at the appropriate state, we headed to Port Mahon for another attempted turnstone catch. One net was quickly set and we retreated to wait for the birds to return. I was lucky enough to be on the firing box for the catch and was given a briefing by Kevin before he settled down to watch the catching area. As the catch potential intensified, the instruction was given to ‘arm the box’. Next came the instruction to ‘connect the cable’, followed by ‘switch in the net’. At this point, the nerves started to hit hard. All I had to do was to press the red button but the pressure to not mess up the catch weighed heavy. When the countdown began, I concentrated hard on the button (remembering not to be distracted by the birds), waited for the instruction to ‘fire’ and plunged my thumb into the button. I was very relieved to hear a resounding ‘boom’ and to see the net go flying over some birds.

The lift was a very wet one but the birds were soon safely in boxes and back at base camp. Before long the keeping cages were full of fifty turnstone and two processing teams were busy flagging, ringing and processing birds. I scribed for this catch which was interesting due to the differences in the British and American terminology and coding systems. It was a nice, efficient catch, including our first re-traps of the season, which helped to boost the current, somewhat low (so far) ringing totals.

After a bit of downtime at the house, I joined the team heading into Mispillion Harbour to re-sight. We weren’t expecting much, as a mid-afternoon recce hadn’t seen many birds out there. Our pessimism was, however, totally unfounded and we were treated to Back Beach looking far more like how I remembered it from last year. Unfortunately, most of the birds were dunlin but there were about 400 – 500 knot, a few turnstone, a few semis and dowitchers and the odd sanderling. It was our first opportunity to get a decent number of knot re-sightings and I managed to get forty-two flags into the notebook. By 7pm it was beginning to get a bit chilly and the birds were getting a little flighty which gave us fabulous views of the birds in flight. There can be few views more spectacular as the sun is beginning to set than the sight of twenty thousand birds flying around in front of you!

Swarms of birds on Back Beach
On Saturday, Rob, Guy and I skived off from re-sighting and accepted an invitation to join the Sussex County Bird Club / Delaware Audubon on a birding trip to the Great Cyprus Swamp in the south west of Delaware State. The area is a privately owned habitat that is managed for deer. It has previously been drained but is currently undergoing management work to try to restore the habitat to its former glory. This includes removing the trees (sweet gums / tulip poplars) that are colonising the drier areas and re-wetting the woodland. The trees being removed are being ring-barked, leaving large numbers of ‘snags’. The by-product of this is a large increase in the number of red-headed woodpeckers. We managed to see ten! The trip generated an additional six new species for me including a cracking male American redstart, yellow-throated warbler, Louisiana water thrush and wild turkey. We also managed to see a black rat snake hassling ovenbirds (some very worried looking adults trying to protect their chicks) and tiger swallowtail butterflies (both the yellow and the black morphs) – stunning!!! Unfortunately, woodland birding is not that conducive to photography, particularly as the birds were being especially secretive and difficult to see, so there is no photographic evidence of any of the new species.

When we returned to Slaughter Beach we diverted straight to the DuPont Nature Centre to help out at the Peace, Love and Horseshoe Crabs event. This involved showing the few visitors that were left to see what few birds we could find for them at high tide. Unfortunately, the day was nothing like yesterday and was instead, grey and cold and by the time the crew went into Mispillion Harbour, it was also pretty damp. I was quite glad I wasn’t on the trip that evening! I instead stayed at the house and helped to welcome the new intake of Brits (Lucy, Dave and Justin) who arrived to join the seven of us already here.

So, we are still awaiting the arrival of the knot in any large numbers but we are still hopeful…
