I’m late writing this post because we’re still recovering from our marathon hike around Big Bend, looking for some very tricky species. In the end we were on the trail, from first light, for eight hours, walked a dozen miles or more and climbed and descended several thousand feet. Thankfully the temperature wasn’t quite as hot as the previous day but it was in the 90’s by the time we finished. When we’d finally recovered enough to go for supper the temperature at our motel was 109 degrees. So what did this herculean effort produce? Well a good list of interesting birds but alas not our target Colima Warbler, nor our back-up bird of Blue-throated Hummingbird. Both specialist Big Bend species – the warbler was obviously having a day off and, according to local birders, the hummer has yet to arrive. It certainly wasn’t a lack of effort which failed to add these special birds to our list – more likely the topsy-turvy world of global migration.
