Enemy Yours Duck Departure

Sample sizes of mallard (Anas platyrhynchos), gadwall (Mareca strepera), and cinnamon teal (Anas cyanoptera) nests that had small video cameras deployed to determine the timing of the start of hatch (the time at which the first duckling fully emerged from an egg), end of hatch (the time at which the last duckling was fully emerged from an egg), duckling departure from the nest, egg depredation in the 2 days prior to expected hatch, and duckling depredation at the nest

As duckling broods begin to hatch, multiple developmental changes happen simultaneously, making it a challenge to ascertain if one aspect is more or less important in determining the timing of duckling departure from the nest. The extended brooding period for some nests may have resulted from developmental differences among duckling broods or other factors not accounted for in this study. It may have taken longer for some broods to hatch than other broods that began hatch earlier, and therefore, they needed more total time for the ducklings to dry and be physically able to leave the nest. Additionally, these hens may have chosen to wait longer at the nest after hatch than other broods that began hatch earlier, to allow more of their ducklings to make it through the critical period of imprinting prior to departure from the nest. Some eggs may fail to hatch, causing the hen to wait at the nest for a longer period before leaving the nest. We visually inspected our data for potential relationships between departure strategy and aspects of clutch size, including the number of eggs that hatched or failed to hatch, and we did not detect any trends. Additionally, the length of time that we observed to hatch the entire brood should not have delayed departure from the nest for these broods that began hatch later in the day, based on our observations of hatch duration. What we did observe, however, were multiple nests with broods that were fully hatched by early afternoon (13:00 hr) and remained at the nest until the next morning. If predation risk to the ducklings at the nest was the most important factor in the hen's decision regarding when to leave the nest (i.e., more important than predation risk to the ducklings off the nest), we would have expected more broods to have left the nest on the same day that hatch ended instead of waiting at the nest for an additional night prior to leaving the nest. With daylight lasting until at least 19:50 hr local time, there should have been ample time for ducklings that hatched prior to 13:00 hr to dry and be physically able to leave the nest with the hen prior to darkness, although this decision would have come at the expense of imprinting on the hen.

You'll receive a notification once X-ray reaches their popup point--you will need to pop up as well once this happens. Fly up until you spot the hostiles on your Radar Warning Receiver (RWR). Refer to the RWR's HUD overlay and target the radar signature at the far right of the HUD with your TGP. This will be one of the two SAM S/A Radars at the lakefront; these will be the biggest threats to you and X-ray. Use an AGM-161 cruise missile to destroy this target. Use the TGP's GPS-S feature to mark them with a GPS waypoint and hit them with a 161. Once the missile is out, duck down behind the hills and vector to the east to dispatch the second S/A Radar at the enemy airbase. Once you reach the east end of the hills, turn left and use your TGP to mark the RWR blip farthest to the right on your HUD. Like before, mark it with GPS-S, make sure the new waypoint is selected, and use a 161 to destroy it from afar. Once this missile is out, immediately bank right and make for the hills to avoid any SAM sites that could be targeting you. The enemy fighters will now likely be a priority threat. Turn back around and switch your fighter's Radar on to search for the enemy fighters. You are looking for some ASF-58s over the lakeshore. Some of them may be coming for you if you're unlucky. Get up close to them and hit them with heat-seeking missiles, as they are resistant to radar locks. 2ff7e9595c
