The mild February allowed farmers to cut and incorporate cover crops, like vetch, much earlier. CWA’s Egg Salvage Program rescues duck nests from agricultural fields prior to harvest and this helps us assess breeding activity in ag lands. Sacramento ValleyĬultivated rice fields provide the majority of summer water for ducks in the Sac Valley, but quality nesting habitat is scarce. However, this kind of population growth also depends on nesting habitat conditions in April through June, brood-rearing success June through August and molting survival in July and August. ![]() The increased number of hens that nested in 20 and survived the duck season likely returned this year, along with their female offspring, to produce even more ducks. Fortunately, we did not have 100-degree heat waves until late June, after peak hatch.Īlthough the California 20 breeding duck surveys were lackluster, they showed incremental progress back toward the long-term average. Long stretches of high temperatures can kill embryos and reduce hatch success. The pleasant spring temperatures we experienced throughout California this year were good for nesting ducks, too. Both Tim Hermansen, manager of the Upper Butte Basin Wildlife Area, and Dave Van Baren, environmental scientist at Gray Lodge Wildlife Area, said nesting uplands looked good in May, thanks to late-spring rains. Los Banos Wildlife Area Manager Sean Allen saw breeding pairs much earlier than usual, likely due to the early spring. Public-land managers had mixed reports about the breeding ducks and broods they were seeing on the landscape. This is not good news for California ducks. In the big picture, 2020 was the third-driest year since surveys began in the Sacramento Valley and Grasslands, and the second driest in Northeastern California.ĭucks that breed in California make up 19% of our total harvest, and nearly 85% of all California breeding ducks nest in these three regions. Some regions got a few late-spring rains in May, but that did little for our overall water situation. We had an arid winter and the driest February on record. The most important thing to note is that 2020 was one of the driest years here in recent history. Keep in mind that even when we have survey results, it’s difficult to predict the hunting season because weather plays a large role in daily movements, migration and ultimately hunter success. In brief: Conditions in 2020 ranged from poor to excellent.īelow, we’ll review important areas that send ducks our way each year. So, without it, we did the next best thing: We reached out to a vast network of biologists and land managers to ask them what they were seeing on breeding grounds from California to the Arctic. Unfortunately, that’s the data we usually use to forecast the fall flight. They were canceled due to stay-at-home orders and border closings. Due to the COVID-19 pandemic, waterfowl population data collected through annual surveys and banding on northern breeding grounds did not take place this year. You’re likely accustomed to hearing those words by now.

Both age and intoxication should be considered when managing these patients. ![]() In addition, alcohol intoxication also affects injury pattern in people who have fallen down a flight of stairs, increasing the risk of traumatic brain injury. Older patients who fall down a flight of stairs are significantly different from their younger counterparts, with a different injury pattern and a greater likelihood of polytrauma. Intoxicated patients were more likely to suffer injuries to the head and neck (42.9% versus 30.5% p = 0.006) and were significantly younger than sober patients (53 versus 69 years p < 0.001). Older patients were more likely to suffer injuries to all body regions and sustained more severe injuries to the spine they were also more likely to suffer polytrauma (23.6% versus 10.6% p < 0.001). This was a retrospective observational study of prospectively collected trauma registry data from a major trauma centre in the United Kingdom comparing older and younger adult patients admitted to the Emergency Department following a fall down a flight of stairs between July 2012 and March 2015. ![]() The aim of this study was to compare the impact of age and alcohol intoxication on injury pattern and severity in patients who fell down a flight of stairs. Falling down a flight of stairs is a common injury mechanism in major trauma patients, but little research has been undertaken into the impact of age and alcohol intoxication on the injury patterns of these patients.
