A Common Sandpiper and a Cormorant were present at the breakwater by Westview Park.
A visit to North Front Cemetery produced two Redstarts, a Subalpine Warbler, two Sardinian Warbler, three Whitethroats, two Willow Warblers, two Bonelli's Warblers, a Pied Flycatcher and two Woodchat Shrikes.
10 Apr: Overcast skies with heavy levanter cloud down to 200m, with fog over Windmill Hill in the morning. Some light drizzle during the morning, with some sunny spells at midday low cloud returning with light drizzle until late afternoon when levanter cloud cleared giving clear skies in the evening. Winds moderate easterly dying down to light variable in the evening.
The ringing total did not reflect the fall of migrants at Windmill Hill. This may have been due to the low cloud that enveloped the Rock all the way down past the Observatory. Several flocks of Bee-eaters were heard, a White Stork flew north in the dense cloud, and a flock of 7 Siskins landed in the Eucalyptus beside the Observatory.

There was a Whinchat at the Midtown Park.
08 Apr: Levanter cloud over the Rock, town and harbour in a moderate to fresh easterly wind. Very few migrants about, and windy conditions at the netting site prevented a better catch.

07 Apr: Mainly clear skies in the morning with some high cloud, with light variable to light northerly winds at the head of the Bay, and moderate south-westerly in the Strait. Winds turned to a fresh to strong easterly at 14:00hrs, with levanter cloud developing.
A Woodchat Shrike was present at Westview Promenade, and a Sparrowhawk was seen from the Observatory.
06 Apr: Mainly clear skies with some wisps of levanter cloud. Winds light easterly. Unfortunately clear skies did not augur well for migrant passerine activity as the table shows. Also conditions were getting rather warm by mid morning, and the decision to close was met.

04 Cloudy start to the day clearing at midday to give sunny spells. Winds fresh westerly with fresh south-west in the Strait, but winds decreasing by 15:00 with a moderate south-westerly in the Strait, but light winds over mainland Spain. Raptor passage picked up by midday and there was a flurry of soaring birds until 15:00hrs when passage dropped to a trickle and then ceased altogether.

Two Jackdaws were reported flying north over Windmill Hill. A Northern Wheatear and a Woodchat Shrike were observed at North Front Cemetery.
03 Apr: Mainly clear skies with a light to moderate northerly in the morning. Winds then turned to north-westerly by midday and then WNW, with a fresh south-westerly in the Strait. Passage was very slow in the morning, with plenty of Bee-eater flocks heard overhead heading north. A few Swallows and House Martins were also seen, and resident Pallid Swift flocks gathered to feed off the western cliffs of Windmill Hill. At midday, as winds freshened from the west, raptors begun to approach the Rock, and continued until sundown.

02 Apr: Cloudy skies with sunny spells, especially in the afternoon. Winds light northerly, turning to north-westerly by mid morning, and fresh south-westerly in the Strait. Bee-eaters were already passing at dawn, with their melodious call heard constantly from the Observatory. Most raptors passed from midday onwards as westerly winds freshened. Flocks of Pallid Swifts gathered to feed off Lathbury area and Windmill Hill, and observing their antics I came across a Swift with a distinct white rump. Watching it for several minutes, it was obviously a Little Swift, only the second Gibraltar record. The first record was one seen over the South Mole on the 8th August.

A Subalpine Warbler flew into a window at the Fire Station and was rescued by the Rehabilitation Unit. A Short-toed Eagle was killed by the Peregrine on Mediterranean Steps. The eagle feel into the sea. The Environmental Protection Unit also picked up two dead Sparrowhawks that had been killed by gulls. One was rescued at Catalan Bay.
01 Apr: Overcast skies with heavy levanter cloud early in the morning with a light easterly wind. By mid morning levanter cloud diminished with high westerly cloud approaching as winds became light variable. Visibility remained poor and you could not see the Moroccan coastline and Spanish hills because of Saharan dust. As day broke, and the levanter cloud cleared, flocks of Bee-eaters continued to pass overhead at the Observatory all morning. Also heading north were four Tree Pipits, four Meadow Pipits, a Yellow Wagtail, several small flocks of Swallows, four Goldfinches and single Linnet and Serin. A flock of six Black Kites, a Sparrowhawk and two Kestrels also headed north. The sun broke through mid morning, although rather hazy, and flocks of Pallid Swifts and an Alpine Swift gathered to feed over the south District, and off Europa Point.
