The third generation began including a 30-pin dock connector, allowing for FireWire or USB connectivity. This provided better compatibility with non-Apple machines, as most of them did not have FireWire ports at the time. Eventually Apple began shipping iPods with USB cables instead of FireWire, although the latter was available separately. As of the first-generation iPod Nano and the fifth-generation iPod Classic, Apple discontinued using FireWire for data transfer (while still allowing for use of FireWire to charge the device) in an attempt to reduce cost and form factor. As of the second-generation iPod Touch and the fourth-generation iPod Nano, FireWire charging ability has been removed. The second-, third-, and fourth-generation iPod Shuffle uses a single 3.5 mm minijack phone connector which acts as both a headphone jack and a data port for the dock.

Birds occupy a wide range of ecological positions. While some birds are generalists, others are highly specialised in their habitat or food requirements. Even within a single habitat, such as a forest, the niches occupied by different species of birds vary, with some species feeding in the forest canopy, others beneath the canopy, and still others on the forest floor. Forest birds may be insectivores, frugivores, and nectarivores. Aquatic birds generally feed by fishing, plant eating, and piracy or kleptoparasitism. Birds of prey specialise in hunting mammals or other birds, while vultures are specialised scavengers. Avivores are animals that are specialized at preying on birds.
What type of birds may be either insectivores, frugivores and nectarivores?
Forest birds

A week after the implementation of the no-fly zone, NATO announced that it would be enforced. On 30 April a NATO airstrike killed Gaddafi's sixth son and three of his grandsons in Tripoli, though Gaddafi and his wife were unharmed. Western officials remained divided over whether Gaddafi was a legitimate military target under the U.N. Security Council resolution. U.S. Secretary of Defense Robert Gates said that NATO was "not targeting Gaddafi specifically" but that his command-and-control facilities were legitimate targets—including a facility inside his sprawling Tripoli compound that was hit with airstrikes on 25 April.
At the time of these events, what was Robert Gates' title?
