Dutch birds in Hong Kong?

On February 10, 2000, the Hong Kong postal administration issued a stamp block featuring images of European bird species. The proportions of the birds relative to each other are completely wrong, but well, for the true birder, that is no objection. From left to right on the sheet, we see the cow heron (Bubulcus ibes) which originally came from Africa, but was also seen in our area a few years ago Biesbosch. In Hong Kong This bird is also found in the northern part of the New Territories. There, they are often seen sitting on the backs of livestock, picking parasites from their skin. The orange color of the feathers is only seen during the breeding season. For the rest of the year, they are covered in white feathers. In addition, two are flying. European spoonbills (Platalea leucorodia). They are immediately recognizable by the broad tip of their beak. Rare in the Netherlands, but they are being observed increasingly often, especially on the Wadden Islands and the marginal lakes along the IJsselmeerIn Hong Kong, they are still found in the Ramsar area. De little egret (Egretta garzetta) also occurs in the Netherlands. It is the most widespread heron species in Europe. However, it is also the most common heron species in Hong Kong, especially in the New Territories. The stilt (Himantopus himantopus) is also no stranger to the Netherlands, even though this species is much less common than the common avocet. It is more of a bird from Southern Europe and North Africa. This bird, too, should primarily be sought in the Ramsar area of ​​Hong Kong. The largest bird depicted is the Smyrna kingfisher (Halcyon smymensis). This one has never been seen in the Netherlands. It has been seen in Southeast Europe and Northeast Africa. In the Netherlands, we are familiar with the common kingfisher (Alcedo atthis), but it is very rare. In Hong Kong, the bird is common in the New Territories. In the background of the block is the Mai Po Inner Deep Bay visible on the side of the Ramsar area. And on the stamp? Featuring the Tsing Ma Bridge, the sixth largest suspension bridge in the world. The bridge is named after two islands in Hong Kong: Tsing Yi en Ma WanThe bridge has two decks, the upper one being a six-lane motorway and the lower one having two railway tracks, as well as two service roads. The bridge is 1.377 meters long and 206 meters high. The bridge was completed in May 1977 and was opened by Margaret Thatcher. Now, a few words about the technical details of the block. The design of the block was produced by Arde LAM in Hong Kong based on an illustration by Loraine LEE. Here, the birds are indeed shown in the correct proportions! The block was printed by Hélio Courvoisier SA in Switzerland. This stamp printing plant was closed in April 2001 and acquired by the British printing company Walsall Security Printers in June 2001. The block was issued on the occasion of the stamp exhibition held from 1 to 5 February 2001. Hong Kong 2001 Stamp ExhibitionThe theme was nature. But what does that suspension bridge have to do with nature? Or was it intended as a hangout for bored birds?
