We all hope that they were able to breed successfully in the Northern Hemisphere and that they can find food throughout the Flyway to return to our shores. Our resident shorebirds have started to breed in the last few weeks and there are numerous Pied Oystercatcher nests along our shores right now.

The highly specialized foraging strategy of flamingos makes them vulnerable to the effect of subtle changes in habitat quality. Egg harvesting to sell as food was intensive then, with thousands taken annually from the breeding colonies in Chile. Egg collection for local consumption still continues at lower scale.

Within a group, 1–7 male co-breeders compete for matings with 1–3 joint-nesting females who lay their eggs in the same nest cavity. Groups may also contain up to 10 male and female non-breeding helpers, usually offspring of the group produced in prior years 1.

In China, wherever there is one real tourist attraction (like the Great Wall), the local strategy seems to be to add some fake attractions – replicas of palaces or tombs, amusement parks, shopping centers – in order to maximize the income from tourists. But the starting point has to be a real attraction, not a fake one.

All three species mentioned in this article breed on these islands, but the Piratic Flycatcher employs a truly piratic strategy: the breeding pair targets a recently built woven nest, often by a Yellow Oriole or Yellow-rumped Cacique but they have also been recorded targeting the nests of other flycatchers.

A lovely looking and distinctive sounding bird (so they say, I sadly have not seen one…yet), the Kirtland’s Warbler can only be found during its breeding season in Jack Pine forests 5 to 20 years old in the northern Lower Peninsula of Michigan. It was the end of prescribed burns as part of the Kirtland’s Warbler recovery plan.

During the breeding season, some Cattle Egrets look like teenage girls who have just discovered the existence of make-up, and consequently massively overdo it. While having somebody else raise your chicks like an attractive strategy to me, it is not without dangers. It is probably all downhill from here. What’s next?

They are two strikingly different strategies, both of which seem to working well this spring, as everywhere one turns there is new life on the Tundra. Horned Larks breed widely over North America, including up here in the High Arctic. They are fed by one or both parents, even after they’ve fledged and left the nest.

One of the more interesting aspects (in my opinion) of breeding in birds is their mating strategy. There are four main mating strategies in birds: 1) monogamy, 2) polygyny, 3) polyandry, and 4) polygynandry. The final, rarest mating strategy, found in less than 0.1% of all bird species, is polyandry.

Within the bird world, so many different strategies and methods of mating and reproduction have evolved, it simply boggles the mind. When it comes to breeding, Yellow-rumped Warblers are a good example of what many people regard as a “regular” bird. Other infamous brood parasites include cowbirds and Old World cuckoos.

Gisela Kaplan has written a book about the species, and how they seem unperturbed by humans: “It’s one of their most successful defense strategies. When these birds breed, this can lead to highly cringeworthy announcements, for example from Adelaide Zoo : “We have egg-citing news! ” ( source ).

Unfortunately, the Ashy Drongos did not exactly do what he predicted that they would do – mob potential predators more frequently during the breeding season and mob the more dangerous predator (in this case, the Black Eagle) more intensely. Well, maybe some hardcore creationists, I guess.

It is kind of rare to see a Fairy Pitta during Shanghai’s spring migration as those passing through are all adults rather than inexperienced chicks, and they are in a rush getting to their breeding grounds – but I was lucky.

I have written about the interesting sex life of these jacanas a few times already (short version: female mates with male, lays a bunch of eggs for him to incubate and raise the chicks, leaves him, finds another male, repeat). Apparently, after a male first mates with a female, he throws out the first one or two eggs she lays in their nest.
